JDK-6612359 - Nimbus L&F: NetBeans 6.0 Beta 1 causes exceptions with 1.6.0_05-ea-b04
Description
OPERATING SYSTEM(S):
Microsoft Windows XP [Version 5.1.2600]

FULL JDK VERSION(S):
java version "1.6.0_11"
Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode)

DESCRIPTION:
Similar NPEs were fixed in 6u10 under CR 6612359.

Start JConsole from the commandline using the Nimbus look & feel:

jconsole -J-Dswing.defaultlaf=com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel

The main window opens, but when creating the 'Connect to..' dialog, we get a NPE:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Comments
Impact=Low, GUI is usable without Nimbus Likelihood=Low, people normally don' specify -J-Dswing.defaultlaf=com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel Workaround=High, no known workaround exists, excapt not using Nimbus at all. LLH => P5
