What might be special, in this case is: there are two interfaces containing a enum with the same name: interface ItfPipChnlIo { enum Enmactivationtype {} } interface ItfPip { enum Enmactivationtype {} } Perhaps this creates the problem?
We use full signatures everywhere so it *shouldnt* be a problem to have two inner enums with the same name. Is there any way you can share the project with me that has the failure? I feel that is the fastest way to resolution. I will try coding up a representative app but I'm not optimistic I can recreate. Possibly related to the $ getting mishandled for the inner type but feels like that would have come up before if it were a problem.
I had a go but I can't trigger the problem. If you can't share a program I'd at least need more info on the kind of pointcut being used and the general flow through the method dbFct_Connect_DUTs_to_power_supply which seems to be the one causing the issue. Stack map frames must be generated at jump destinations in the byte code. So if there are multiple routes through a method, where those routes re-combine is where we would get into trouble like this (where they recombine is where we have to verify every route to that point agrees on the type of the variables and the stack contents). Does the method have lots of branching? Are variables assigned differing flavors of the enum types in those branches?
The aspect looks like this: public aspect LibAspect { pointcut libFunc() : ( @annotation(castle.anno.SpecText) || @annotation(castle.anno.ILibExport) ) && execution(!static public void *(..) throws !* ); void around() :libFunc() { // .... } } The method causing the problem: @SpecText(/*...*/) public void dbFct_Connect_DUT_to_CASTLE_Private_and_Vehicle_BUS(String DUT) { getPIPChnlIO(DUT).afcBusInjectFault(Enmactivationtype.DISABLED, Enmbusfaulttype.OPENPRIVATEBUS); exu.pauseStandard(); getPIPChnlIO(DUT).afcBusInjectFault(Enmactivationtype.DISABLED, Enmbusfaulttype.OPENVEHICLEBUS); }
It is perhaps interesting that I think your other bug is related to a missing type problem - since both of these issues would then be related to missing types. Or at least types not being found. AspectJ does not actual type finding itself, instead it relies on the class loaders it is being associated with, using their getResource...() methods to find things. If those methods were misbehaving in some way I could see this happening. For example if the delegation model for class lookup is doing one thing but the delegation model for resource locating is doing something else. (Just thinking out loud here).
