This is an attempt to make the FlushCustomClassLoader more stable. I cannot reproduce this bug so added some improvement blindly, based on assumption that the test may fail on the slow/overloaded system.

  • The attempt limitation was removed, but the test execution time decreased to 1 minute
  • For each attempt the generation of OOM was added to make sure that the GC was triggered


  • Change must not contain extraneous whitespace
  • Commit message must refer to an issue
  • Change must be properly reviewed


  • JDK-8276819: javax/print/PrintServiceLookup/ fails to free
