I've said it over and over, year after year, I've written it in our process documentation, I've communicated it through emails: Never ever put any confidential information in the description of a bug. Regardless if the bug concerns a closed feature or internal tests - at some point in the future we might want to open the bug. If I've had a dime for every time I was right I would finally get my first dime.

The bug was filed in 2013, it's about JFR which at the time was an Oracle internal feature. As JFR has been open sourced I'd be happy to open the bug, but the description of the bug contains confidential information (for no good reason, as always). There is no point in cleaning up the description since the old description will still be available in the history of the bug.

I'll share the bulk of the details below, let me know if you need more.

Relates to: JDK-8155219 - [TESTBUG] Rewrite compiler/ciReplay/TestVM.sh in java

Comments:

ILW=LMH=P5. Not a production feature. Intermittent. No known workaround.

This test is going to be rewritten in java by JDK-8155219, so, problem might be gone after that.

after rewriting to java, test(renamed) still fails:
