[jira] Commented: (HARMONY-2656) [classlib][awt] Compatibility: java.awt.AreaAveragingScaleFilter.setPixels() throws different Exceptions on RI and Harmony when the height is negative

Andrey Pavlenko commented on HARMONY-2656:
------------------------------------------

The issue is in the negative height passed to the AreaAveragingScaleFilter() constructor. RI does not throw any Exceptions in this case, but I don't think it's a valid behavior. I think this issue should be closed as non-bug diff.
