When an applet class files are distributed in multiple jar files specified in the applet html's archive , cache_archive or preload options.The progress bar pops up and hangs .Doesn't load the applet.This behaviour is seen only if the
multiple jar files needed to run the applet are specified in any of the archive,cache_archive, preload parameters.I was able to reprodcue this probelm on Windows 2000, NT and solaris.

In the test case A.class has run method and is in A.jar and calling B.class in B.jar .

Scenarios 1 :

If a.jar and b.jar are in archive or cache_archive or preload then progress bar hangs .

Scenarios 2:
If a.jar is in archive and b.jar is in cache_archive or preload the applet runs fine.Thus limiting only one jar file per tag.

The above scenarios are tested with the same test applet which has a run method.Looks like it happend only when running thread as i tried simple
classes was not able to reproduce.suspect some threading related problem.

Test Cases

Jar files specified in archive tag.
