For example, if you have a memory leak issue where you want to understand why certain are not marked for garbage collection; or you are troubleshooting the classloading conflict issues in Pega product (e.g., why a specific class is loaded by Websphere but not from the Pega classloader (from the database).

Classloading problems can take various forms. You may get noclassdeffoundexception, classcastexception or compilation errors since the loaded class does not have the necessary method for Activity/Library compilation.

We'd prefer it if you saw us at our best.
