I confirmed that `java/util/concurrent/Executors/UnreferencedExecutor.java` still fails if the [fix applied to ThreadContainers.java](https://github.com/openjdk/jdk/commit/ada416e66cbff6c8e631bf352acc0744c248740b#diff-1e347b9a95cc4fe81a01ca70e4122a73a65d99a69668c7567abb2a6067f8cc6dL68) is reverted. ------------- PR Comment: https://git.openjdk.org/jdk/pull/18098#issuecomment-1975231258
