8264052: Shenandoah: Backout 8263832 #3158

wants to merge 1 commit into from

@zhengyu123 zhengyu123 commented Mar 23, 2021

TestStringDedupStress started to fail after JDK-8263832.

JDK-8263832 is incorrect, because Threads::possibly_parallel_threads_do() only iterates over Java and VM threads, it should be backed out. The original works correctly.
