> Can I please get a review of this change which proposes to improve the code > in `get_user_name_slow` function, which is used to identify the target JVM > owner's user name? This addresses https://bugs.openjdk.org/browse/JDK-8321971. > > As noted in that JBS issue, in its current form, the nested loop ends up > iterating over the directory contents of `hsperfdata_xxx` directory and then > for each iteration it checks if the name of the entry matches the pid. This > iteration shouldn't be needed and instead one could look for a file named > `<pid>` within that directory. > > No new test has been added, given the nature of this change. Existing tier1, > tier2, tier3 and svc_tools tests pass with this change on Linux, Windows and > macosx.
