Please find below a fix for 8052403: java/util/logging/CheckZombieLockTest.java fails with NoSuchFileException https://bugs.openjdk.java.net/browse/JDK-8052403 The issue here is that CheckZombieLockTest and CheckLockLocationTest use (create and delete) the same writable-dir under /tmp. When jtreg is run with a high concurrency factor this sometimes results in one of the tests deleting the directory that the other is running. I could verify this by triggering the same failure with: jtreg -verbose:all -jdk $MYJDK -conc:12 \ jdk/test/java/util/logging/Check* The fix simply arranges for CheckZombieLockTest to use a different directory than that used by CheckLockLocationTest (and also improves the diagnostic by arranging for setUp() to fail fast if the test lock file cannot be created).
