This is a regression from b87.

EVALUATION I suggest closing this as a duplicate of AWT bug 6436388, which is the same problem, and fixing it under that bug number.

EVALUATION It's actually another instance of 6434148. The fix of 6434148 only take cares of all the occurrences of the problem in the swing workspace. But this time, the problem comes from awt :( In the static initializer of java.awt.TestArea, it uses TreeSet to store KeyStroke, which is the same problem as 6434148. A simple standalone testcase will reproduce the same exception: class test { public static void main(String[] args) { new java.awt.TextArea(); } } C:\6436388>"c:\Program Files\java\jre1.6.0\bin\java.exe" test Exception in thread "main" java.lang.ExceptionInInitializerError at test.main(test.java:3) Caused by: java.lang.ClassCastException: java.awt.AWTKeyStroke cannot be cast to java.lang.Comparable at java.util.TreeMap.compare(Unknown Source) at java.util.TreeMap.put(Unknown Source) at java.util.TreeSet.add(Unknown Source) at java.awt.KeyboardFocusManager.initFocusTraversalKeysSet(Unknown Sourc e) at java.awt.TextArea.<clinit>(Unknown Source) ... 1 more Re-assigning to awt for further investigation.
