So, is there a non-deprecated way to get the class loader of a plug-in
(bundle) in 3.0? My plug-in depends on keeping track of its own class
loader and the class loaders of the plug-ins that use it. The new
Bundle#loadClass() method is not good enough. Should I open a bug for
this request?

Hi I just started writing plugins, so I might be way off. But this sounds similar to what I have done.
My plugin also uses JNDI and I had alot of problems related to the class loader (mainly because I did
not know how eclipse handled classloading (not sure I do even now))

What I did was this something like this....

ClassLoader orig = Thread.currentThread().getContextClassLoader();
try {
Thread.currentThread().setContextClassLoader(MyPlugin.class. getClassLoader());
// Performed my JNDI lookup
....
finally {
Thread.currentThread().setContextClassLoader(orig);
}

Now if someone knows a better way to do this please let me know.
