| Hi,
|
| I have written the following test-aspect, which brings my application to
| crash and at the moment I don't know why, maybe you can give me an hint for
| a solution. Here is my aspect-code:
|
| public aspect MethodCallTraceAspect
| {
| pointcut tracePoints() : call(*
| sms.library.ValidityChecker.isPhoneNumberValid(..));
|
| before() : tracePoints()
| {
| System.out.println("Before");
| System.out.println("Entering " + thisJoinPoint);
| }
|
| }
|
| Everything compiles well, but when I start to run it, the WTK emulator
| crashes and I get the following output:

| Maybe this output is correct and has somthing to do with the fact, that I am
| using an obfuscator. But why then my application crashes, cause usually, it
| shouldn't terminate the program. Any ideas?

I am not sure this can help (moreover I have no knowledge about j2me envs): I've heard sometime ago
that the ClassLoaders are not available in j2me env. Maybe the aspect generated code uses some
class.getClassLoader() invocation this triggering the crash.
