Summary: trouble launching drjava after windows java upgrade

Initial Comment:
This is probably a bug in Sun's JDK installer, but I've 
had similar reports from students, so it may be worth 
documenting, even if nothing can be done.

Environment: Windows XP pro, JDK 1.3.1, 1.4.0, 1.4.1, 
DrJava versions: several of the recent stable builds.

Symptom: Double-clicking the drjava.jar file doesn't 
launch and brings up the "select program to open" 
dialog box.  javaw is not listed in the initial dialog that 
pops up and browsing to javaw.exe and opening it is 
apparently ignored - it still doesn't appear on the list, 
and can't be selected.

I managed to reproduce this, twice, when trying to 
upgrade one machine from jdk 1.3.1_03 to 1.4.1_02 and 
another one from 1.4.0_03 to 1.4.1_02.  Steps:

- Install a different version of the jdk (1.4.1_02) on a 
machine with a previous version installed (1.3.1 or 1.4.0).

- Delete the previous version leaving just 1.4.1_02.  At 
that point double-clicking a jar file won't launch it, and 
javaw can't be selected to launch it.

The only workaround I've discovered is to completely 
delete everything related to Java, including java web 
start, and reinstall the latest version.  (It may be 
necessary to select javaw the first time a .jar file is 
double-clicked, but javaw is available in the list and can 
be selected.)  Deleting the jdk and jre and reinstalling 
those is not enough - if java web start is left on the 
machine, the problem remains.

Again, likely to be a sun installer/uninstaller bug, but if 
someone can figure out what's happening, that'd be 
great.

Hal
