Why is this an error?  I don't believe EXIT_ON_CLOSE is valid for
JInternalFrame.

EXIT_ON_CLOSE is specific to JFrames.

I have seen something similar in JDialog and or JFrame. Invalid values should
not throw an exception but should instead be swallowed and lead to the default
behaviour, AFAICR.

No exception seems to be thrown anymore.
