Hi Bengt,
it may require some tweak on the etc/jre.properties, to prevent the JVM
to load some classes.
Could you share your etc/org.ops4j.pax.logging.cfg file to try to
reproduce the issue ?
Thanks,
Regards
JB

I have the strangest of problems on one of my installations. I have a

Windows Server 2003 SP2, I cannot start Karaf correctly due to the
following:

I then tried with a standard Karaf 2.3.0 and got the exact same error.
The above errors only show up in the console since the logging system
cannot initialize properly. It seems like a strange classloading issue
but I fail to understand how it can happen. It looks like the JVM itself
has loaded log4j classes making them incompatible with the "real" ones.
Has anyone seen this before? Any clues?
It's 32 bit Windows and I've tried with java 1.6.0_29 as well as 1.6.0_37.
