Benjamin Reed updated KARAF-3090:
---------------------------------
Attachment: karaf-2.3.5-startInstance.patch
Turns out the problem is in AdminServiceImpl.java. If the karaf.opts properties
is null *and* $KARAF_OPTS environment variable isn't set, karafOpts ends up
being null, and there is no null-check.
Attached is a one-liner that fixes it. I was gonna update the unit test to
handle this failure, but there's no unit test for startInstance(). ;)
