--------------------------------------

I had time this morning to download 5.4.0.Final and my unit tests all pass using the current version.  Sorry for wasting your time with this bug from an old release.

> String comparison using the == operator fails in some cases.  "Fails" means the comparison should match but does not.  Changing the condition to use equals() operator causes a successful match.  I have observed this in both decision tables and in drl rules.  I will attach a test case that reproduces the bug.  There are workarounds to avoid the bug - the test case demonstrates 3 of them.
