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

[Andrus Adamchik]

Hmm... actually looking closer at the stack, this has nothing to do  
with initialization of descriptors. This is some circular object  
faulting. Still a DataMap would help.

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?
