--------------------------------

Thanks Josh for trying it out.
{quote}I feel like trying to get all of these warnings suppressed is chasing 
your tail for little good :(

 I share this opinion with you. I feel the same. Let's stall this then?

> 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.
> {code:java}
> WARNING: An illegal reflective access operation has occurred
> WARNING: Illegal reflective access by 
> org.apache.hadoop.hbase.util.UnsafeAvailChecker 
> (file:/Users/jatsakthi/test/HBASE_TEST_AREA/hbase-3.0.0-SNAPSHOT/lib/hbase-common-3.0.0-SNAPSHOT.jar)
>  to method java.nio.Bits.unaligned()
> WARNING: Please consider reporting this to the maintainers of 
> org.apache.hadoop.hbase.util.UnsafeAvailChecker
> WARNING: Use --illegal-access=warn to enable warnings of further illegal 
> reflective access operations
> WARNING: All illegal access operations will be denied in a future release
