Subject Re: jaxb 2.2 problem in osgi branch
Date Thu, 05 May 2011 00:00:34 GMT
I solved this problem, at least for car-maven-plugin, by setting the bootdelegation to include
all the com.sun packages in the class library other than com.sun.xml.bind.  I wish there was
an exclusion syntax for the bootdelegation property.

Further thoughts are definitely welcome....

of com.sun packages turned on.

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.

-Pstage-bootstrap to get the car-maven-plugin to build the first time.
