Can we close this issue? Is a OOME you are getting?

> When inserting a number of facts, (seems to be somewhere around 450 facts in this test example here), the rules system exits unexpectedly with no stack trace or other information.  I pared down my code to a simple example that demonstrates this below.  I can get it to run normally if I insert 450 facts, however 475 or above exhibits this unexpected system exit.  I am running this from Eclipse.
