             Summary: Suppress Java 11 Unsafe warnings
                 Key: HBASE-22172
                 URL: https://issues.apache.org/jira/browse/HBASE-22172
             Project: HBase
          Issue Type: Bug
            Reporter: Sakthi
            Assignee: Sakthi


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
