    On a fresh install of CentOS 7 with OpenJDK 1.8, running karaf container versions > 4.0.2 either with "bin/karaf" or as a service (whether sysvinit or systemd), trying to log in with "bin/client" always fails with an exception. Oracle JDK - by comparison - works. "git bisect" narrowed down the regression to the following commit: 539540cde099aee52fd523a09aca92e36522261c is the first bad commit commit 539540cde099aee52fd523a09aca92e36522261c Author: Freeman Fang <freeman.fang@gmail.com> Date: Wed Oct 14 12:09:09 2015 +0800 [KARAF-4062]Karaf client does now work after installing BouncyCastle :040000 040000 926f15997510a671ff77db9623f8b65ce4186706 da83c22e043de3004a620f1cc88e25ee672bd09d M client The exception is: # bin/client Logging in as karaf 3771 [sshd-SshClient[593634ad]-nio2-thread-2] WARN org.apache.sshd.client.session.ClientSessionImpl - Exception caught java.lang.IllegalStateException: Unable to negotiate key exchange for kex algorithms (client: ecdh-sha2-nistp256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp384,ecdh-sha2-nistp521,ecdh-sha2-nistp521 / server: diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1) at org.apache.sshd.common.session.AbstractSession.negotiate(AbstractSession.java:1159) at org.apache.sshd.common.session.AbstractSession.doHandleMessage(AbstractSession.java:388) at org.apache.sshd.common.session.AbstractSession.handleMessage(AbstractSession.java:326) at org.apache.sshd.client.session.ClientSessionImpl.handleMessage(ClientSessionImpl.java:306) at org.apache.sshd.common.session.AbstractSession.decode(AbstractSession.java:780) at org.apache.sshd.common.session.AbstractSession.messageReceived(AbstractSession.java:308) at org.apache.sshd.common.AbstractSessionIoHandler.messageReceived(AbstractSessionIoHandler.java:54) at org.apache.sshd.common.io.nio2.Nio2Session$1.onCompleted(Nio2Session.java:184) at org.apache.sshd.common.io.nio2.Nio2Session$1.onCompleted(Nio2Session.java:170) at org.apache.sshd.common.io.nio2.Nio2CompletionHandler$1.run(Nio2CompletionHandler.java:32) at java.security.AccessController.doPrivileged(Native Method) at org.apache.sshd.common.io.nio2.Nio2CompletionHandler.completed(Nio2CompletionHandler.java:30) at sun.nio.ch.Invoker.invokeUnchecked(Invoker.java:126) at sun.nio.ch.Invoker$2.run(Invoker.java:218) at sun.nio.ch.AsynchronousChannelGroupImpl$1.run(AsynchronousChannelGroupImpl.java:112) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Authentication failed
