ClassesByName2Test.java and RedefineCrossEvent.java failing with jtreg tip

This two tests are not selected (meaning they are not run) by jtreg 4.2 b02. The test selection issue has been fixed in jtreg tip so that these tests are selected but unfortunately they fail with:

                        javax.rmi.CORBA.Util.getCodebase(this.getClass());
                                       ^
1 error
result: Failed. Compilation failed: Compilation failed

Both tests use @run driver and so will need to be examined to see how they work with modules (they need to run with -addmods java.corba).
