Another (which seems as likely in this case) appending too much data to 
an automatically resizing buffer, such as a StringBuilder, or ArrayList. 
  Given the stack trace, it appears the be an ArrayList.

It could be the OP needs to increase the memory allowed. It also could 
be that too much data is being submitted (looks like a RPC<->gwt bridge, 
maybe they are sending the whole world).
