Noticed one thing.

test/hotspot/jtreg/runtime/cds/appcds/aotClassLinking/StringConcatStress.java line 37:

> 35:  * @test id=aot
> 36:  * @requires vm.cds
> 37:  * @requires vm.cds.supports.aot.class.linking

>From the VMProps.java in the mainline:

    protected String vmCDSSupportsAOTClassLinking() {
      // Currently, the VM supports AOTClassLinking as long as it's able to write archived java heap.
      return vmCDSCanWriteArchivedJavaHeap();
    }

The `vmCDSCanWriteArchivedJavaHeap()` already checks for `vmCDS()`.
So it seems the `@requires vm.cds` is redundant.
