Adrian Brock closed JBMICROCONT-223.
------------------------------------

    Resolution: Done

This has been fixed by handling getPackage(s) requests using similar rules
to the class and resource delegation.

Sealing violation checking has been added.

> The package handling is not working properly in the new classloader.
> 1) In the new classloader each classloader has no parent (unlike the old UnifiedClassLoader - UCL).
> Instead the parent is a Loader. This means that packages in the parent (e.g. the classpath) are not visible
> 2) In both the old and new classloader, packages are not retrieved across the peers
> this means that each classloader gets its own package object.
> This means that package sealing does not work.
> 3) Since the sealing check is in the URLClassLoader, the new classloader is not performing
> this check - it uses the SecureClassLoader
