Comment 1 Dani Megert CLA 2002-12-17 05:11:45 EST 
Can't reproduce on Win2k.
rt.jar from which SDK?
Comment 2 Dani Megert CLA 2002-12-17 05:12:43 EST 
Can reproduce now.
This is a must fix for 2.1 M4.
Comment 3 Dani Megert CLA 2002-12-17 05:37:45 EST 
Note that for internal JARs the label is wrong: it always shows the name of the
JAR (no NPE though).
Comment 4 Dani Megert CLA 2002-12-17 06:23:01 EST 
Attached patch
Comment 5 Dani Megert CLA 2002-12-17 06:39:00 EST
