John Ross commented on ARIES-927:
---------------------------------
I intend to release the changes in
aries927-areMultipleFrameworksAvailable.patch by the end of today without
objection.
> Imports org.osgi.service.framework package as optional but assumes it's there
> nevertheless.

> Util imports the org.osgi.service.framework package as optional. However, the
> InternalRecursiveBundleTracker invokes "x instanceof CompositeBundle" in the
> addingBundle() method without protection. This results in a
> NoClassDefFoundError, like the one below, in environments where the package
> is not available. One such environment is the OSGi CT, where "private"
> package imports, such as the x-internal org.osgi.service.framework package
> provided by Equinox, are forbidden.
