@TheShermanTanker I have now created https://bugs.openjdk.java.net/browse/JDK-8280863 for you. To get access, you need to get Author status in the JDK project, which you can get by submitting repeated high-quality PRs.

Please update the bug title to read "8280863" and the proper format will be filled in for you.
