Mark Proctor commented on JBRULES-1060:
---------------------------------------

notice you have a nested loop:
            for (int i = 1; i <= 3; i++) {
                for (int j = 1; j <= 475; j++) {
so thats actually 1425 facts its attempting to insert.

> 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.
