John Ross updated ARIES-927:
----------------------------
Attachment: aries927-areMultipleFrameworksAvailable.patch
Yes, I see what you're saying. The BlueprintExtender creates a
RecursiveBundleTracker which won't create an InternalRecursiveBundleTracker if
areMultipleFrameworksAvailable() returns false. However, the current check
there is not sufficient because Equinox will register the
org.osgi.service.framework.CompositeBundleFactory service even though the
corresponding package is x-internal and resolution mode is strict. So the
service is there, but the Util bundle does not have access to the
org.osgi.service.framework package. Moving the additional check to
RecursiveBundleTracker.areMultipleFrameworksAvailable() solves the issue just
as well and is fine with me. The latest patch incorporates that idea and would
replace the previous patch.

> 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.
