Looks good.  It seems that it's introduced by the patch for 8182879 (confidential bug). Just for the reference, 8u patch with this issue https://github.com/openjdk/jdk8u-dev/commit/a2d837f50cc792cbbce56aa3892a169ff5f7b297 and 11u patch without this issue https://github.com/openjdk/jdk11u-dev/commit/7cf3c0ff1482d23494f88a0eaf13a821adc0bc47
