Re: testing M5 - StackOverflowError during context.deleteObject()

Fri, 05 Dec 2008 06:01:42 -0800

In theory current ClassDescriptor "compiler" is prone to stack overflows because descriptors often try to access info from other descriptors before they are fully initialized, causing circular descriptor faulting. I saw that often during development, however I thought I addressed all cases. Can you send me a DataMap that caused this stack?

Hello.
Sorry for being so slow, but I just now started testing M5 with our internal junit tests. It did not go that well. a context.deleteObject() caused a StackOverflowError. Anyone else seen this?
