Considering the fact that we are accessing the private members of sun.nio,
java.lang.reflect etc. All those will fail. Any code using setAccessible(true)
will fail to work. Java 9 suggests some alternate for this (not sure whether we
will have a better work around when the actual release happens).
Alternate includes adding these extns to JVM
(for eg)
{code}
--add-exports=java.base/sun.nio.ch=ALL-UNNAMED
--add-opens=java.base/java.lang.reflect=ALL-UNNAMED
{code}
Just adding it here as I could see this JIRA as the umbrella JIRA.

A number of internal {{com.sun}} classes will be removed, including Unsafe.
These removals need to be handled or HBase will not be able to run on a Java 9
runtime. Doing this in a backwards compatible way may be tricky. I'm not sure
how Oracle will navigate to where they want to go while dealing with unfixable
user code breakage and I hope we have an opportunity to provide pushback on
changes if required.
I don't think we need to do anything today beyond track what others in the
ecosystem are doing, for example
Considering Java 9

Key: HBASE-12081
URL: https://issues.apache.org/jira/browse/HBASE-12081
Project: HBase
Issue Type: Umbrella
Reporter: Andrew Purtell
Java 9 will ship in 2016. This will be the first Java release that makes a
significant compatibility departure from earlier runtimes.

I picked recent releases except for HBase and Optiq, which I built from source. For Optiq because I could not find a binary distribution at the time. For HBase I used 0.99-SNAPSHOT because it has the new dependencies on Netty 4 and the LMAX Disruptor that will be in the upcoming 1.0 release. There are some common dependencies (Netty, Guava, Derby, the Scala runtime, Coda Hale's Metrics, LMAX Disruptor) that use internal sun.* APIs. We would need versions of these dependencies which do not make those calls available before we could eliminate internal API calls through this route. Other uses fall into a few common patterns. Daemons use Signal/SignalHandler for catching signals. Datastores such as HBase, Hive, and Cassandra are seeking their own high performance optimizations with Unsafe, including direct memory allocation. Avro and Kyro are serialization libraries seeking high performance via Unsafe on hot code paths. Hadoop and HBase utilize some security APIs for Kerberos and SSL which seem to have no non-internal API analogues. Pig and HBase pull in Jython and JRuby, respectively. Jython uses a bit of Unsafe. JRuby is an aggressive user of JVM internals.
