    Description



      Name: rmT116609 Date: 05/05/2004


      FULL PRODUCT VERSION :
      java version "1.4.2_04"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
      Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows 2000 [Version 5.00.2195] SP 4

      A DESCRIPTION OF THE PROBLEM :
      Since 1.4.2, the JDK will create shared memory perfdata in a folder named hsperfdata_user in the temp directory. This only works, if the temp directory is on a NTFS partition under Windows 2000.

      If I set this to "E:\Temp", where E:\ is a FAT32 partition, then shared perfdata is not available and I cannot connect to the JVM with tools like jvmstat.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Create a FAT32 partition E:set TMP=E:\Temp
      Start any java program.
      hsperfdata_user folder is not being generated.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      hsperfdata should be available, also if temp dir is on a FAT32 partition.
      ACTUAL -
      No hsperfdata.

      REPRODUCIBILITY :
      This bug can be reproduced always.

      CUSTOMER SUBMITTED WORKAROUND :
      Use NTFS partition for TMP directory.
