java.lang.StackOverflowError coming frequently (Talend MDM)

Hi
This is same topic as in http://www.talendforge.org/forum/viewtopic.php?pid=99228 . The error is coming frequently when any job contains 9-10 numbers of sub-elements. This is a kind of show-stopper error as the same sub-elements is running fine in another job with same input. I am using Talend Open Studio For MDM (Version: 5.2.0M1). Please help. Is there any limitation of sub-elements?
Any solution/clue will be great.
Thanks -
Sunrej
