ClassFormatError
While working with MVCSoft-pm a ClassFormatError occured. The cause of this error has been determined (thanks to Dan from MVCSoft). One thing is still unclear to me howerver. A ClassCastException occurs while propagating the Error. If I am interpreting the stacktrace correctley this would be on line 854 of EntityContainer.java. This is in the catch-block dealing with RuntimeExceptions. Now how does my ClassFormatError end up there?
