             Summary: Cassandra support for JDK 9
                 Key: CASSANDRA-11987
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11987
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: JDK9
            Reporter: shylaja kokoori


Hi,

I tried to compile Cassandra with JDK 9 and ran into compilation issues because 
monitorEnter/monitorExit functions have been removed from sun.misc.Unsafe in 
JDK9 
(http://mail.openjdk.java.net/pipermail/jdk9-hs-rt-changes/2015-January/000773.html).

Is there a specific reason why Cassandra uses these Unsafe APIs instead of say 
java.util.concurrent.locks?

Thanks,
shylaja
