   * @requires vm.cds.archived.java.heap
+  * @comment This test explicitly chooses the type of GC to be used by sub-processes. It may conflict with the GC type set
+  * via the -vmoptions command line option of JTREG. vm.gc==null will help the test case to discard the explicitly passed
+  * vm options.
