FULL PRODUCT VERSION :
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)
FULL OPERATING SYSTEM VERSION :
SunOS wind 5.7 Generic_106541-23 sun4u sparc SUNW,Ultra-60
A DESCRIPTION OF THE PROBLEM :
I ran your new swing demos that show off 1.4 features. In
particular I ran the ActionDemo located here:
http://java.sun.com/docs/books/tutorialJWS/uiswing/misc/example-1dot4/ActionDemo.jnlp
It launches just fine and correctly uses the Metal look and
feel for the top level window dressing, however if I grab
the toolbar and detatch it such that it creates a top level
shell you will notice that it ignores the
setDefaultLookAndFeelDecorated hint given to the top level
frame and displays the shell using the Motif window
dressings. This looks really bizzar.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Load the following link with Java Web Start
http://java.sun.com/docs/books/tutorialJWS/uiswing/misc/example-1dot4/ActionDemo.jnlp
2. Grab the toolbar handle and tear it off the application
so that it floats in it's own top level shell.
3. Note that the window dressing is the native one instead
of using the Metal look and feel like the top level frame did.
EXPECTED VERSUS ACTUAL BEHAVIOR :
I expected all child shells to use the same hint as the top
level frame from which it came.
REPRODUCIBILITY :
This bug can be reproduced always.

/*
* This relies on having the Java Look and Feel Graphics Repository
* (jlfgr-1_0.jar) in the class path. You can download this file
* from http://developer.java.sun.com/developer/techDocs/hi/repository/.
* Put it in the class path using one of the following commands
* (assuming jlfgr-1_0.jar is in a subdirectory named jars):
*
* java -cp .;jars/jlfgr-1_0.jar ActionDemo [ customer Windows]
* java -cp .:jars/jlfgr-1_0.jar ActionDemo [UNIX]
*
* I needed to put quotation marks around the path, since I use a
* UNIX-emulating shell on Win32:
*
* java -cp ".;jars/jlfgr-1_0.jar" ActionDemo [UNIX shell on Win32]
