Sakthi commented on HBASE-22172:
--------------------------------
I tried to run a PE with --illegal-access=warn to list out all such warnings.
Here's what I have so far:

> Suppress Java 11 reflective access warnings

> Reporter: Sakthi

> Priority: Major
> Labels: jdk11

> 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.
