I have a problem with the classloader and I am not able to understand the exact cause of the ERROR. Please find the error output from the server logs attached.
Here the Class JobGetPollerData tries to Access a 'protected' method from TimerManager and the exception is thrown. As Scott suggested I read the class loader docs. From my understanding, if two different class loaders are used to load classes and if on tries to access the other this exception is thrown. So tried to print the Classloader for both the classes, and it is loaded by the same class "org.jboss.mx.loading.UnifiedClassLoader".
So could you please explain, what is the issue here?
Thanks Muraly
