      Description

      ZGC currently calls ThreadLocalAllocBuffer::resize() regardless of if -XX:ResizeTLAB is enabled or not. This causes the following assert to fail:

      # Internal Error (open/src/hotspot/share/gc/shared/threadLocalAllocBuffer.cpp:130), pid=22060, tid=22069
      # assert(ResizeTLAB) failed: Should not call this otherwise
