OutOfMemoryError with using DefaultMessageFactory and quickfixj-all-1.6.1.jar

Hi,
after upgrade from 1.5.3 to 1.6.1 I got "OutOfMemoryError". I'm using "quickfixj-all-1.6.1.jar". Problem is that "quickfix.DefaultMessageFactory" trying to add all factories (fix40,fix41,..fix50sp2). Problem is during adding "fix50sp2".

I had to use "quickfixj-all-1.6.1.jar" instead of "quickfixj-core-1.6.1.jar" + "quickfixj-messages-fix44-1.6.1.jar" because of issue "QFJ-845".

Please, could you look at it? Is there a plan for release a new quickfixj version?

Thank you.

Error replication:
MessageFactory mf = new DefaultMessageFactory();
