Sorry I wasn't clearer in my original post. It's been a while since I looked at this issue.
My particular problem is that the generated field wrapper inner classes don't get assigned the correct protection domain. Here's a stack trace that shows the problem occuring.

| main():463, FrameworkLoader.java

The toClass method of StandaloneClassPool does the following:
| Class cl = Class.forName("java.lang.ClassLoader");
| java.lang.reflect.Method method
| = cl.getDeclaredMethod("defineClass",
| new Class[]{String.class, byte[].class,
| int.class, int.class});
|
My classloader doesn't get a chance to define the class, causing the field wrappers to be assigned a default protection domain.
So, what's actually needed is for the class pool to use the correct classloader when calling defineClass.
Hope that helps.
Tim.
