Backport request for JDK-8034773

[Jaikiran Pai]

One of the projects I watch, has run into an issue[1] which has been
fixed in Java 9+. The fix for Java 9+ went in as part of this issue[2].
The related commit for it is [3] and includes more than one bug fix. The
commit itself is relatively small and has a testcase included.

I am new to the backport request process. What would be the best way
forward to have this change backported to OpenJDK 8? Should I be raising
a backport request in the JBS (I've "author" role, so can do that if
that's necessary)?

Right now, the issue has been worked around[4] in the project where we
hit it. But I would like to avoid more such changes all over the place,
by having this fixed in OpenJDK itself.
