Thank you for the comment, I've prepared a fix that follows this way:

  http://cr.openjdk.java.net/~akozlov/8249677/webrev.00/

The change also brings consistency with observable jdk11u logic. The test case from lucene-solr passes after applying this, as well as Test.java supplied to the bug.

Could you please review the change?

Thanks,
Anton
