around to answer questions in any case.

--I couldn't get the xml stream 1.2 and jaxb 2.2 to work with the spec jars as bundles.  
 According to
even if you do get them to work (as we seem to have up to now by not exposing the packages
from the framework) that breaks other stuff.  I think we need to investigate the karaf-activator
stuff guillaume wrote and adapt our specs to use it.  At the moment I have the framework lying
and claiming later versions for the xmlstream and jaxb packages.  I haven't found any documentation
for karaf-activator yet.

-- the build uses a lot more memory.  I typically run out of permgen twice during the build
with MAVEN_OPTS =  -XX:MaxPermSize=512m -Xms1024m -Xmx2048m

-- startup AFAIK only works as ./bin/karaf -l rather than our geronimo scripts.  Again, I
have to increase memory settings for the server to fully start.
