      Running TEST=gc/InfiniteList.java JTREG_JAVA_OPTIONS='-XX:+UseParallelGC -XX:+UseNUMA' with debug build results in the following failure

      # Internal Error (~/src/hotspot/share/gc/parallel/mutableNUMASpace.cpp:279), pid=1354464, tid=1354473
      # assert(clear_space) failed: Reallocation will destroy data!

      The bug is due to Parallel NUMA doesn't support eden-expansion when eden is not empty. The incorrect logic was added in "JDK-8338977 Parallel: Improve heap resizing heuristics"
