[cp-patches] RFC: Class Loader patch to record class with initiating class loader

[Jeroen Frijters]

Hi,

While digging around the class loading issues, I discovered that we
didn't record a class with the "initiating loader" [1]. This is
necessary to maintain type safety in the face of buggy or malicious
class loaders (or even when the contents of the directories in the
classpath change).

I've also attached a Mauve test case that checks for everything I could
think of. These tests pass on IBM JDK 1.3, Sun JDK 1.4, Sun JDK 1.5 and
my local IKVM version.

Please comment.

Regards,
Jeroen
