    - Fix an incompletely interpolated dependency with maven 4.0.0-rc-4
    - Fix wrong invocation of xmvn-subst
    - Updated to upstream version 2.14.0
    - Changes in version 2.14.0      + GH-524 Performance improvements      + GH-533 Fix multi-step authentication      + GH-582 Fix filtering in NamedFactory      + GH-587 Prevent NullPointerExceptionon closed channel in      NettyIoSession      + GH-590 Better support for FIPS      + GH-597 Pass on Charset in      ClientSession.executeRemoteCommand()      + New utility methods SftpClient.put(Path localFile, String      remoteFileName) and SftpClient.put(InputStream in, String      remoteFileName) facilitate SFTP file uploading.
     * GH-590 Better support for FIPS      Besides fixing a bug with bc-fips (the RandomGenerator class      exists in normal Bouncy Castle, but not in the FIPS version,      but Apache MINA sshd referenced it even if only bc-fips was      present), support was improved for running in an environment      restricted by FIPS.
     There is a new system property      org.apache.sshd.security.fipsEnabled. If set to true, a number      of crypto-algorithms not approved by FIPS 140 are disabled:
     + key exchange methods sntrup761x25519-sha512,      sntrup761x25519-sha512@openssh.com, curve25519-sha256,      curve25519-sha256@libssh.org, curve448-sha512.
     + the chacha20-poly1305 cipher.
     + the bcrypt KDF used in encrypted private key files in      OpenSSH format.
     + all ed25519 keys and signatures.
     Additionally, the new 'SunJCEWrapper' SecurityProviderRegistrar      (see below) and the EdDSASecurityProviderRegistrar are      disabled, and the BouncyCastleScurityProviderRegistrar looks      only for the 'BCFIPS' security provider, not for the normal      'BC' provider.
     If the system property is not set to true, FIPS mode can be      enabled programmatically by calling SecurityUtils.setFipsMode()      before any other call to Apache MINA sshd.
     * Potential compatibility issues      + New security provider registrar      There is a new SecurityProviderRegistrar that is registered      by default if there is a SunJCE security provider. It uses      the AES and HmacSHA* implementations from SunJCE even if      Bouncy Castle is also registered. SunJCE has native      implementations, whereas Bouncy Castle may not.
     The new registrar has the name 'SunJCEWrapper' and can be      configured like any other registrar. It can be disabled via      the system property      org.apache.sshd.security.provider.SunJCEWrapper.enabled=false.
     It is also disabled in FIPS mode (see above).
     The methods NamedFactory.setupBuiltinFactories(boolean      ignoreUnsupported, ...) and      NamedFactory.setupTransformedFactories(boolean      ignoreUnsupported, ...) had a bug that gave the      'ignoreUnsupported' parameter actually the meaning of      'include unsupported'.
     This was fixed in this release, but existing code calling      these or one of the following methods:
     ~ BaseBuilder.setUpDefaultMacs(boolean ignoreUnsupported)      ~ BaseBuilder.setUpDefaultCiphers(boolean ignoreUnsupported)      ~ ClientBuilder.setUpDefaultCompressionFactories(boolean      ignoreUnsupported)      ~ ClientBuilder.setUpDefaultKeyExchanges(boolean      ~ ClientBuilder.setUpDefaultSignatureFactories(boolean      ~ ServerBuilder.setUpDefaultCompressionFactories(boolean      ~ ServerBuilder.setUpDefaultKeyExchanges(boolean      ~ ServerBuilder.setUpDefaultSignatureFactories(boolean      ~ any of the methods starting with      SshConfigFileReader.configure      ~ SshClientConfigFileReader.configure(...)      ~ SshServerConfigFileReader.configure(...)      should be reviewed:
     ~ if the method is called with parameter value true, the      result will no longer include unsupported algorithms.
     Formerly it wrongly did.
     ~ if the method is called with parameter value false, the      result may include unsupported algorithms. Formerly it      did not.
     So if existing code used parameter value false to ensure it      never got unsupported algorithms, change it to true.
     * Major Code Re-factoring      + JDK requirements      ~ GH-536 The project now requires JDK 17 at build time, while      the target runtime still remains unchanged to support JDK      8.
    - Changes in version 2.13.2

     This uses a post-quantum key encapsulation method (KEM) to      make key exchange future-proof against quantum attacks.

     + Behavioral changes and enhancements      ~ GH-318 Handle cascaded proxy jumps      Proxy jumps can be configured via host configuration      entries in two ways. First, proxies can be chained directly      by specifiying several proxies in one ProxyJump directive:
     Host target      Hostname somewhere.example.org      User some_user      IdentityFile ~/.ssh/some_id      ProxyJump jumphost2, jumphost1      Host jumphost1      Hostname jumphost1@example.org      User jumphost1_user      IdentityFile ~/.ssh/id_jumphost1      Host jumphost2      Hostname jumphost2@example.org      User jumphost2_user      IdentityFile ~/.ssh/id_jumphost2      Connecting to server target will first connect to      jumphost1, then tunnel through to jumphost2, and finally      tunnel to target. So the full connection will be      client->jumphost1->jumphost2->target.
     Such proxy jump chains were already supported in Apache      MINA SSHD.
     Newly, Apache MINA SSHD also supports cascading proxy      jumps, so a configuration like      ProxyJump jumphost2      ProxyJump jumphost1      also works now, and produces the same connection      It is possible to mis-configure such proxy jump cascades to      have loops. (For instance, if host jumphost1 in the above      example had a ProxyJump jumphost2 directive.) To catch such      misconfigurations, Apache MINA SSHD imposes an upper limit      on the total number of proxy jumps in a connection. An      exception is thrown if there are more than      CoreModuleProperties.MAX_PROXY_JUMPS proxy jumps in a      connection. The default value of this property is 10. Most      real uses of proxy jumps will have one or maybe two proxy      jumps only.
     ~ GH-461 Fix heartbeats with wantReply=true      The client-side heartbeat mechanism has been updated. Such      heartbeats are configured via the      CoreModuleProperties.HEARTBEAT_INTERVAL property. If this      interval is > 0, heartbeats are sent to the server.
     Previously these heartbeats could also be configured with a      CoreModuleProperties.HEARTBEAT_REPLY_WAIT timeout. If the      timeout was <= 0, the client would just send heartbeat      requests without expecting any answers. If the timeout was      > 0, the client would send requests with a flag indicating      that the server should reply. The client would then wait      for the specified duration for the reply and would      terminate the connection if none was received.
     This mechanism could cause trouble if the timeout was      fairly long and the server was slow to respond. A timeout      longer than the interval could also delay subsequent      heartbeats.
     The CoreModuleProperties.HEARTBEAT_REPLY_WAIT property is      now deprecated.
     There is a new configuration property      CoreModuleProperties.HEARTBEAT_NO_REPLY_MAX instead. It      defines a limit for the number of heartbeats sent without      receiving a reply before a session is terminated. If the      value is <= 0, the client still sends heartbeats without      expecting any reply. If the value is > 0, the client will      request a reply from the server for each heartbeat message,      and it will terminate the connection if the number of      unanswered heartbeats reaches      CoreModuleProperties.HEARTBEAT_NO_REPLY_MAX.
     This new way to configure heartbeats aligns with the      OpenSSH configuration options ServerAliveInterval and      ServerAliveCountMax.
     For compatibility with older configurations that explicitly      define CoreModuleProperties.HEARTBEAT_REPLY_WAIT, the new      code maps this to the new configuration (but only if      CoreModuleProperties.HEARTBEAT_INTERVAL > 0 and the new      property CoreModuleProperties.HEARTBEAT_NO_REPLY_MAX has      not been set) by setting      CoreModuleProperties.HEARTBEAT_NO_REPLY_MAX to      = CoreModuleProperties.HEARTBEAT_REPLY_WAIT <= 0:
     CoreModuleProperties.HEARTBEAT_NO_REPLY_MAX = 0      = otherwise: (CoreModuleProperties.HEARTBEAT_REPLY_WAIT /      CoreModuleProperties.HEARTBEAT_INTERVAL) + 1.
     ~ GH-468 SFTP: validate length of data received: must not be      more than requested      SFTP read operations now check the amount of data they get      back. If it's more than requested an exception is thrown.
     SFTP servers must never return more data than the client      requested, but it appears that there are some that do so.
     If property SftpModuleProperties.TOLERATE_EXCESS_DATA is      set to true, a warning is logged and such excess data is      silently discarded.
     + AES-CBC ciphers removed from server's defaults      The AES-CBC ciphers aes128-cbc, aes192-cbc, and aes256-cbc      have been removed from the default list of cipher algorithms      that a server proposes in the key exchange. OpenSSH has      removed these cipher algorithms from the server proposal in      2014, and has removed them from the client proposal in 2017.
     The cipher implementations still exist but they are not      enabled by default. Existing code that explicitly sets the      cipher factories is unaffected. Code that relies on the      default settings will newly create a server that does not      support the CBC-mode ciphers. To enable the CBC-mode ciphers,      one can use for instance      SshServer server = ServerBuilder.builder()      ...
     .cipherFactories(BuiltinFactory.setUpFactories(false,      BaseBuilder.DEFAULT_CIPHERS_PREFERENCES));
     .build();
     For the SSH client, the CBC ciphers are still enabled by      default to facilitate connecting to legacy servers. We plan      to remove the CBC ciphers from the client's defaults in the      next release.
