A DESCRIPTION OF THE PROBLEM :

There's no API-doc for MetalLookAndFeel.setCurrentTheme() method. Can we have multiple MetalLookAndFeel with different MetalTheme in one AppContext?

 Actually, we are restricted to have only one MetalTheme in one AppContext. When we call setCurrentTheme(), it will partially affects component's rendering even if we did not call setLookAndFeel() nor updateUI(). Some properties are
changed, some are not.

 This is a different case from 4804502. 4804502 is obviously a bug because AppContext is different. In this case, we are in one AppContext, and the specification of setCurrentTheme itself is ambiguous.


REPRODUCIBILITY :
This bug can be reproduced always.
