Cloning bug to backport to 3.7.2.


+++ This bug was initially created as a clone of Bug #361390 +++

Build Identifier: 3.7.0.v20110613

When working with Apache Aries in an environment running on an IBM J9 JVM, the 'class data sharing' adapter for eclipse is returning a shared class cache token to the framework out of a class loading hook.  The token is then getting passed to the OSGi weaving hooks where the weavers are falling because the class bytes are invalid.

Perhaps there should be a mechanism where the framework attempts to verify that the byte code returned from load hook has a proper byte code magic of 'CAFEBABE' before passing it to the weaving hooks?


Reproducible: Always

Steps to Reproduce:
1. Run equinox on an IBM JDK with the CDS framework extension
2. Enable a weaving hook
3. Note that the weaving hook does not get class bytes by the shared class cache token
