What
With #350 it looks like a null-pointer has been tried to access. This happens randomly, after maybe 5 mins or so.
My gut feeling tells me that this is the Java garbage collector running exactly at the point where a frame processor is being invoked, and since we only pass the frame, the parameters and the return values as
alias_ref(non-ref counted pointers), Java thinks it can delete those values. Now I tried using a thread specific ref-counted pointer (local_ref) and it seems like everything is working - need feedback from #350's OP first though.Changes
