FULL PRODUCT VERSION :
doesn't matter

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Dell Precision 450 Dual 2.4 gighz CPU, 1 gig Ram. Hyperthreading on.

A DESCRIPTION OF THE PROBLEM :
We have two Dell Precision 450 Dual 2.4 gighz CPU, 1 gig Ram. The following problem only happens on these two computers when we install java 1.5, 1.5 update 1, or 1.5 update 2. Other computer install just fine. Others have also reported this problem. See http://forum.java.sun.com/thread.jspa?threadID=571871.

Using the Windows Task Manger. At the time the install is frozen there is a javaw.exe running. It is using 0% CPU. Just before the installation stalls there is no javaw.exe running. Also the classes.jsa, "Class Data Sharing", file is incomplete (0 KB). After restart this file is 5,701,632 bytes. It is impossible to kill this javaw.exe. I tried using the "End Process" button and the taskkill.exe command to kill it. Ever time you type java from the command line. Each of these java processes are also unkillable. Also shutting down the computer or restarting is also impossible without physically powering down the computer.

After restart java.exe works, but if you try run java with java -Xshare:on you get the following error:

An error has occured while processing the shared archive file.
The shared archive file has the wrong version.
Error occurred during initialization of VM
Unable to use shared archive.

My guess is that the freeze occurs when the install is trying to create the "Class Data Sharing" file.



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Get a computer that the problem occurs on such as Dell Precision 450 Dual 2.4 gighz CPU, 1 gig Ram. Hyperthreading on. Run the install.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The installation completes.
ACTUAL -
In the Windows Task Mangager the installer and javaw.exe are using 0% cpu. The javaw.exe is impossible to kill. Unable to shutdown or restart without physically hitting the reset button on the computer case.

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
1. Install 1.5 jdk.

2. Watch Windows Task Manager. Installation freezes as soon as javaw.exe shows up in the window.

3. Hard Restart. You can try to kill javaw.exe. But you won't be able to.

4. Execute "java -Xshare:on".
An error has occured while processing the shared archive file.
The shared archive file has the wrong version.
Error occurred during initialization of VM
Unable to use shared archive.

This step 4 is required, if not step 6 or 8 will freeze.

5. Check size of classes.jsa (5,701,632 bytes). Optional step. Just here to show classes.jsa is incomplete.

6. Execute "java -Xshare:dump"

9. Check size of classes.jsa (12,517,376 bytes) Optional step. Just here to show classes.jsa is complete.

10. Repeat with JRE Install.
