I haven't seen this, but suspect that it might be causing problems in
the config.xml in the assembled server.
I don't have much a clue how this could be occurring, and haven't
noticed it happening here... I take it from your comments that it
happens while building the assembly?
thanks

Hi,
I ran into some weird LinkageErrors with JAXB classes and I have no
clue what is causing this. I'm hoping somebody might have some ideas
how to deal with it. The most interesting thing is that these errors
are logged but don't actually cause any problems. Also, I see these
errors when I build the framework from the top but not if I build the
framework/assemblies separately.
