        Description

        A bug has been fixed that could cause long "Concurrent Process Non-Strong References" times with ZGC. The bug blocked the GC from making significant progress, and caused both latency and throughput issues for the Java application.

        The long times could be seen in the GC logs when running with `-Xlog:gc*`:
        ```
        [17606.140s][info][gc,phases ] GC(719) Concurrent Process Non-Strong References 25781.928ms
        ```
