Functionality for skipping testsuites on certain platforms fails for the new management testsuite
on phoneME advanced 
----------------------------------------------------------------------------------------------------------------------

                 Key: DERBY-3521
                 URL: https://issues.apache.org/jira/browse/DERBY-3521
             Project: Derby
          Issue Type: Test
          Components: Test
         Environment: phoneME advanced platform
            Reporter: Vemund Østgaard
            Assignee: Vemund Østgaard


It is not possible to run suites.All on phoneME advanced, junit will just exit with an InvocationTargetException
when trying to invoke the suites.All.suite() method. Unwrapping the exception shows that the
underlying reason is a NoClassDefFoundError from the invoke() call in AllPackages.addSuiteByReflection()
when trying to load the new management testsuite.

Now, this suite is compiled into 1.5 classfiles, so the Class.forName() call before the invoke()
is expected to fail with UnsupportedClassVersionError on Java ME and Java SE 1.4. It does
fail as expected when running with jdk 1.4, but on phoneME advanced it does not, possibly
a bug in phoneME advanced.

A fix/workaround in the testinfrastructure may be to catch InvocationTargetException from
the try block below, unwrap it and see if it is an instance of LinkageError and if so skip
the testsuite. This would make it possible to run the tests on phoneME advanced.

private static Test addSuiteByReflection(String className) throws Exception
   {
       try {
           Class clz = Class.forName(className);
                      Method sm = clz.getMethod("suite", null);
                            return (Test) sm.invoke(null, null);
       } catch (LinkageError  e) {
           return new TestSuite("SKIPPED: " + className + " - " +
                   e.getMessage());
       }
   }
