RFR+RFA [11u]: 8165675: Trace event for thread park has incorrect unit for timeout

[Langer, Christoph]

Hi,

may I please get reviews for the downport of 8165675 to jdk11u.

Bug: https://bugs.openjdk.java.net/browse/JDK-8165675
Original Change: http://hg.openjdk.java.net/jdk/jdk/rev/4eff16f47ae2
Backport Webrev: http://cr.openjdk.java.net/~clanger/webrevs/8165675.jdk11u/

The patch did not apply cleanly. There were problems:
src/java.base/share/classes/jdk/internal/event/EventHelper.java
-> the file is not there because a prerequisite change (8148188: Enhance the security libraries to record events of interest) is not in jdk11u. So the diff here simply does not apply.

src/jdk.jfr/share/classes/jdk/jfr/consumer/RecordedObject.java.rej
-> there is a failing hunk for method OffsetDateTime getOffsetDateTime(String name). But this method is not part of jdk11u either, so it does not apply.

src/jdk.jfr/share/classes/jdk/jfr/internal/tool/PrettyWriter.java.rej
-> this class is part of the jfr tool, which was not downported to jdk11u so far. Hence no apply.

I'll run the full test suite before pushing.

Best regards
Christoph
