<Swing Dev> [12] RFR JDK-8213843: Changing L&F from Nimbus to Window L&F causes NPE in SwingSet2

[Prasanta Sadhukhan]

HI Sergey,

I am not sure why which requires some investigation. I see none of the 
Synth*UI class has caching, maybe it was done intentionally. Since it is 
quite close to RDP1 and there are other issues need to be fixed, I would 
like to defer this investigation after RDP2 (when the jdk13 ws would be 
opened). Meanwhile, I would like this fix to go in as it breaks 
SwingSet2 demo.

Regards
Prasanta
