While running tier testing, one existing test showed that I hadn't taken into account SecurityManager checks in the new code that I had added. I have now fixed that part and pushed an update to the PR. There's one additional unrelated test failing (`TestMaxCachedBufferSize`) in a odd way and I'll investigate it separately. ------------- PR: https://git.openjdk.org/jdk/pull/11943
