      Description

      Summary

      Remove the system property jdk.lang.ref.disableClearBeforeEnqueue that was added to restore the Reference::enqueue to JDK 8 behavior, i.e. not to clear the reference object.

      Problem

      The behavior of the Reference::enqueue method was changed in JDK 9 to clear the reference object before enqueuing. A system property jdk.lang.ref.disableClearBeforeEnqueue was added to allow existing code to revert to JDK 8 behavior as an interim solution and give time to migrate to JDK 9 new behavior.

      Solution

      Remove jdk.lang.ref.disableClearBeforeEnqueue system property support.

      Specification

      Setting -Djdk.lang.ref.disableClearBeforeEnqueue=true will have no effect to Reference::enqueue method.

      No spec change since jdk.lang.ref.disableClearBeforeEnqueue system property is undocumented.
