Anybody know what it points to?
My thought was an array out of bounds but never seen anything like this before

Moin,

check if you have to reduce your stack usage.

- Wed Jun 10, 2015 2:45 pm #20079 Each nested method call costs a little bit big arrays as local variables may kill you.
Check your method call chain and your local variables used.
If they exceed a few kbytes thats too much. (Don't have exact number here but may be less than 8kb or 6kb)
