<Swing Dev> RFR: 5015261: JInternalFrame causes NPE [v5]

[Prasanta Sadhukhan]

> JInternalFrame.getDesktopIcon() can be null as setDesktopIcon() can be called with null value. There are many places in JInternalFrame where getDesktopIcon() is accessed without null check which might cause NPE. 
> Added null check for those cases.
