[OJB-developers] bug in ClassDescriptor.getDynamicProxyClass

[Georg S. <ge...@me...>]

Hi Thomas and Jacob,

First of all sorry for always bugging you two to put patches in, but I
simply don't know who is responsible for what part. Is there a list of who
maintains what, if not it would be a good idea to make one :-).

The bug: getDynamicProxyClass creates a proxy class implementing all
interfaces of the original class. In order to do this it first calls
getInterfaces() on the class to be proxied and then iterates over all the
superclasses to do the same.
This works fine if the original class is a real class, which is almost
always the case.
Unfortunately when using a reference-proxy the item class can be an
interface itself and when getInterfaces() is called on an interface it
returns only the extending interfaces, not the interface itself.

Fix: Put the following lines in the method getDynamicProxyClass() in
ClassDescriptor

     Class[] interfaces = clazz.getInterfaces();
==>add from here on
     if (clazz.isInterface())
     {
	Class[] tempInterfaces = new Class[interfaces.length + 1];
	tempInterfaces[0] = clazz;

	System.arraycopy(interfaces,0,tempInterfaces,1,interfaces.length);
	    interfaces = tempInterfaces;
      }


Cheers

Georg
