The bug is reported by EDS PLM Solutions in its development of new J2EE application. They notice drag-n-drop operations cause their java application to hang.

A small test is attached to illustrate the problem. To reproduce the problem, simply do drag-n-drop operations between two list windows.

The Java 1.3.1 is used:
SUN112.SDRC.COM:/scratch/nsjxu/java/dnd3:202$ java -version
java version "1.3.1_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_01)
Java HotSpot(TM) Client VM (build 1.3.1_01, mixed mode)

The systems used here are
Ultra10/Elite3D/Solaris 8
SunBlade 100/Expert3D Lite/Solaris 8 10/00

Here is the patch information on one of systems:

The program works OK on Windows systems.

The test program appears to work fine using the Java 1.4 Beta:
SUN112.SDRC.COM:/scratch/nsjxu/java/dnd3:201$ java -version
java version "1.4.0-beta3"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0-beta3-b84)
