      Description

        JDK-8237369 added assertion to ensure that incoming object is alive outside of marking cycle. But this assertion is unreliable, cause Shenandoah cleans bitmap in concurrent phase, and has_forwarded_object flag can be carried into next GC cycle in piggyback ref-update mode.

        Solution: remove the assertion.
