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. (Incident Review ID: 261067) ======================================================================
