[equinox-dev] BundleFileWrapperFactoryHook

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

I have encountered a couple of nasty
gotchas using wrapBundleFile():
1. BundleFile subclasses do not use
getBaseFile() but use the protected basefile field instead. I got an NPE
because my wrapping BundleFile subclass used the default constructor. Could
the default constructor be made private to avoid this pitfall?
2. Worse is NestedDirBundleFile which
is not wrappable. Is this an oversight or deliberate? It's very important
that my wrapped bundle file handles getEntry() and getResourceURL() differently:
the first I override to find cached classes the second I delegate to ensure
ClassLoader.getResourceAsStream() works correctly (and does not look in
the cache).

Thanks
