Common ForkJoinPool prevents class unloading in some cases

    XMLWordPrintable

Details

    Backports

      Description

        When the ForkJoinPool.commonPool() creates new worker threads, they capture an AccessControlContext from the location where they were created, which means that the class won't get unloaded for the lifetime of that worker thread.
