["Nick Dimiduk (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-22172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17442343#comment-17442343 ] 

Nick Dimiduk commented on HBASE-22172:
--------------------------------------

[~supercharger5] we can upgrade our netty version (see the hbase-thirdparty repo). We still have Hadoop's old version of netty on our class path as a transitive dependency. Until they upgrade their version, we will have runtime warnings.

> 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
