Newer and older Java versions run by a SYSTEM account will have different temp paths, therefore the hsperfdata_username will be in a different place. (I was being picky about attach, but it's a universal thing which is expected to work across different Java versions.) Do we have any apps commonly run as a Windows SYSTEM account which expect to attach to other Java apps run by a different Java version? You're suggesting that will have no impact and agreed it would seem really unusual. 8-) ------------- PR Comment: https://git.openjdk.org/jdk/pull/20600#issuecomment-2343034670
