Anyone have any experience running Equinox using IBM J9?  We are having
some problems with using IBM J9 that we don't encounter with Sun's JVM.

Dennis - 

In a nutshell - The J9 VM packages many javax xml extension jars and
their corresponding apache implementations in the library directory of
the JRE. Many of the same packages are supplied by bundles that ship
with Eclipse. A number of these bundles export packages without version
numbers, and we find ourselves running into class verification errors
when the classes provided by the JRE don't match those expected by the
bundles.  The Sun JVM prepend the apache classes with com.sun., so the
problem is partially mitigated. However, for javax.* classes, the
potential for trouble remains.

Is there a way to alter the contents of the system classpath during osgi
startup such that we can suppress these additional classes provided by
J9 and resolve them from the bundles provided by Eclipse?

Cheers,
Joel
