Mark Proctor commented on JBRULES-904:
--------------------------------------

took me a while to remove all the threading from the system and DataSource stuff. so it all ran in one method :) But once that was done I inserted the minimal information to make it occur. Once I saw why it was happening, it was quick to fix, it wasn't iterating the parent and child linkedlists in the toArray. So there was two bugs for this bug, but this should hopefully be fixed now :)

> I added some println() statements, and it's not an off-by-one error, it's something more serious.  I changed the allocated size of the array to (this.size * 10), and it *still* tried to overfill the array.  The hashtable had 26 entries, but it tried to add 261, and counting.
