@sendaoYan adding to the PL will mean the test never runs. With the proposed change it will still run in tier1_serviceability where it has not been seen to fail, but will no longer run in the problematic tier4 grouping. This seems a reasonable compromise. That said we have modified a number of tests to workaround the CODETOOLS issue, so we could do that here as well.
