Description
tried installing Mustang build 60 on top of Tiger(5.0)
installation. If you invoke "java -X" from cmdline it fails with:

Can't open C:\WINDOWS\system32\Xusage.txt
Comments
EVALUATION The problem is caused by the putback for 6316197, the directory name is resolved by calling the GetModuleHandle on jvm.dll, which returns a NULL, since jvm.dll is not loaded, therefore GetModuleFileName returns back the dirname of java.exe.

EVALUATION Can we reproduce this in house? > Yes, it can be reproduced on my WinXP at home and at work. just install b61 with or without previous 5.0, and run java -X you will get this error message. Is there an env var set or something that is affecting search paths? > did not set any evn var manually, but there is a Java_Home env var set and path includes %Java_Home\bin Which binary is displaying the error message? > java.exe Why is it looking in the system directory? > no clue?

EVALUATION Please verify whether or not the Xusage file is on the system. The code that locates the Xusage file hasn't changed in sometime so I doubt this is a tools issue. Xusage.txt file is under: D:\Program Files\Java\jdk1.6.0\jre\bin\client D:\Program Files\Java\jdk1.6.0\jre\bin\server but not under windows system directory - D:\Windows\system32\Xusage.txt

EVALUATION Did you have the Tiger JRE or JDK already installed? Which version of 5.0? > Yes, 5.0 FCS(b64) Did you install the Mustang JRE or JDK? >Mustang JDK Which directory were you in when you ran this command? >Home direcotry; D:\\Documents and Settings\Ingrid Yao Does the command work when you run it from the 6.0 bin directory? >No, got the same problem. I've got conformation from Ingrid that this also happens when 5.0 isn't installed. This must be a tools issue.
