Karaf 2.3.5
Description
When I start with a completely clean Karaf 2.3.5, I am unable to start a sub-instance.
Steps to reproduce:
ranger@the-slip:/tmp$ tar -xzf apache-karaf-2.3.5.tar.gz
ranger@the-slip:/tmp$ cd apache-karaf-2.3.5
ranger@the-slip:/tmp/apache-karaf-2.3.5$ bin/karaf

Hit '<ctrl-d>' or type 'osgi:shutdown' or 'logout' to shutdown Karaf.

If I try to run that command on the command-line, I get the error:
Error: Could not find or load main class null
Note the "null" after the
-Dcom.sun.management.jmxremote
in the command-line it's trying to send; it appears that javaOpts is somehow ending up with some null junk in it when it attempts to create the call to start the sub-karaf.
I tried digging into the code a bit but I can't figure out which part is responsible for actually creating those javaOpts.
