Thanks go to Andrew Wason <aw@softcom.com> for finding this problem and providing the patch:



If we implement a Java interface in JavaScript, and a method in that interface returns a Java object, we get a java.lang.IncompatibleClassChangeError: org/mozilla/javascript/Wrapper  exception.

We have attached a sample JavaScript file which duplicates the error.

The problem is JavaAdapter is generating an INVOKEVIRTUAL bytecode to call Wrapper.unwrap, but Wrapper is an interface and so INVOKEINTERFACE should be used instead.  As a result of this change, the IFEQ bytecode generated needs to jump more bytes.  We have attached a patch that fixes the problem.
