Andrus Adamchik commented on CAY-1036:
--------------------------------------
I have no information about java 6 behavior, but the error looks similar to what I recently encountered (on Mac and Java 5) when testing the Modeler. IIRC (1) that should already be fixed on trunk and (2) the reason it showed up on one machine but not the other is that fact that the problematic machine had an empty local preferences DB (i.e. the error happens on populating prefs DB for the first time).
So what date is your modeler build? I suggest to update from trunk, rebuild and try it again.
