java.lang.IllegalStateException: Unable to negociate key exchange for item 2

[Taro Fukunaga <ta...@gmail.com>]

Karaf 2.2.3 has the same problem running Karaf as a service under Linux as I
saw in Karaf 2.2.0. The steps to reproduce this are very simple:

1) Start karaf
2) features:install wrapper
3) wrapper:install
4) ^D then karaf-service start
5)  ./client

Session is closed

Solution is to open KARAF_HOME/etc/karaf-wrapper.conf and change two lines.
It says:

wrapper.java.additional.8=-Djava.endorsed.dirs="%JAVA_HOME%/jre/lib/endorsed:%JAVA_HOME%/lib/endorsed:%REPO_DIR%/endorsed"
wrapper.java.additional.9=-Djava.ext.dirs="%JAVA_HOME%/jre/lib/ext:%JAVA_HOME%/lib/ext:%REPO_DIR%/ext"

But should be without quotes:

wrapper.java.additional.7=-Djava.endorsed.dirs=%JAVA_HOME%/jre/lib/endorsed:%JAVA_HOME%/lib/endorsed:%KARAF_HOME%/lib/endorsed
wrapper.java.additional.8=-Djava.ext.dirs=%JAVA_HOME%/jre/lib/ext:%JAVA_HOME%/lib/ext:%KARAF_HOME%/lib/ext

With this fix the client is able to connect. And also karaf log shows lots
of stuff about SSH which is good to see.

Can someone please address this issue so that karaf wrapper also works out
of the box on Linux? Thanks.
