How about translating Type to java.lang.Object? Since the jdk1.5 Type interface does not have any methods, you don't seem to lose any functionality. So the code above becomes | final Object[] OBJ_TYPE_ARR = new Object[] {Object.class}; | If you get the latest jboss retro from svn, this is how I have it working now. Combined with kabir's code, this seems to work. At least for the test cases I came up with. Maybe we lose something else that I'm not thinking of.
