NimbusL&F:The L&F isn't properly applied when switching from NimbusL&F to any other L&F at runtime.
While switching, when the nimbus L&F is unitialized before the new L&F is initialized, some of the properties are not cleared out properly.
This is observed on Nimbus L&F all OS with the current 6u4b02 pit build.
Steps to reproduce:
1)Run SwingSet2 with Nimbus L&F applied with the -Dswing.defaultlaf option.
2)In the "Look & Feel " menu switch to Motif and Windows/GTK L&F (as applicable for a windows/unix OS)
Observe that the new l&f is not applied correctly for all components.
