[icedtea-web] RFC: Fix problem in resolving classes

[Omair Majid]

Hi,

IcedTea-Web currently has a bug where it can not resolve classes under
certain situations. It can trigger when the following sequence of steps
happen:

1. An applet with both a codebase and a jar (archive) is loaded
2. A class is loaded using the codebase loader
3. The class tries to load a class that is specified in the archive

The following applet reproduces the problem:

Thoughts? Comments?

Thanks,
Omair
