I'm writing a Java application that runs on Linux (using Sun's JDK). It keeps creating /tmp/hsperfdata_username
directories, which I would like to prevent. Is there any way to stop java from creating these files?
Try JVM option -XX:-UsePerfData
The following might be helpful that is from link https://docs.oracle.com/javase/8/docs/technotes/tools/unix/java.html
-XX:+UsePerfData
Enables the perfdata feature. This option is enabled by default
to allow JVM monitoring and performance testing. Disabling it
suppresses the creation of the hsperfdata_userid directories.
To disable the perfdata feature, specify -XX:-UsePerfData.
