Nick Dimiduk commented on HBASE-22172:
--------------------------------------
Since we cannot fix our transitive dependencies, I'm in favor of adding these
flags. At the very least, the patch attached here will consolidate the list of
which warnings we suppress and need to investigate as we progress to newer JDK
versions.
[~sakthi] would you mind putting up your patch as a PR? We can get it reviewed
and committed. Thanks.

> While running a Java 8 compiled hbase on Java 11 system, I found the
> following warnings being thrown. I think we can add the "--add-opens" flag to
> HBASE_OPTS (if the jdk version is 11) to suppress this warning.
