Subject Re: jaxb 2.2 problem in osgi branch
Date Wed, 04 May 2011 14:56:03 GMT
The only difference I'm aware of that we have between Karaf and
Geronimo configuration is the org.osgi.framework.bundle.parent
property. Karaf sets it to org.osgi.framework.bundle.parent=framework
while we don't set it in Geronimo and it defaults to "boot". But that
really shouldn't make any difference in this case as far as I can

dds, this works and we are actually using the 2.2 bundle.  We also have boot delegation of
com.sun packages turned on.

feature to install the specs, woodstox, and the jaxb 2.2 impl.  However, now the com.sun
bootdelegation seems to be kicking in so that as soon as the jaxb implementation gets to com.sun
classes they are loaded from the framework/vm rather than the jaxb 2.2 imple bundle.

same bundles seem to be working fine in trunk.
