我在Linux VM上运行Karaf shell，然后尝试使用apache提供的客户端脚本或ssh工具连接到它，在两种情况下都关闭连接。
我按如下所示启动karaf外壳：
[scfuser@europa-16 bin]$ ./karaf
karaf: Ignoring predefined value for KARAF_HOME
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=16M;
support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option

Apache ServiceMix (4.4.1-fuse-07-11)
Hit '<tab>' for a list of available commands
and '[cmd] --help' for help on a specific command.
karaf@root>
然后在一个单独的窗口中按如下方式运行客户端：
[scfuser@europa-16 bin]$ ./client
Session is closed
还尝试打开ssh的调试选项：
[scfuser@europa-16 bin]$ ssh -vvv -p 8101 karaf@localhost -vvv -p 8101
karaf@localhost

更多信息：Java 1.8似乎会发生这种情况，只要此应用程序与Java 1.7一起安装，它就可以正常工作。到目前为止，我注意到的唯一区别是，在java 1.8安装中，servicemix似乎使用了/ etc下的jre.properties文件，它为jre 1.8提供了一个额外的条目，如下所示：
jre-1.8= \
com.sun.org.apache.xalan.internal.xsltc.trax, \
com.sun.org.apache.xerces.internal.dom, \
...
etc.etc.
