             Summary: Run BookKeeper on Java9
                 Key: BOOKKEEPER-1049
                 URL: https://issues.apache.org/jira/browse/BOOKKEEPER-1049
             Project: Bookkeeper
          Issue Type: Improvement
         Environment: java9
            Reporter: Enrico Olivelli
            Assignee: Enrico Olivelli
             Fix For: 4.6.0


I am tring to run BookKeeper on Java9, a part from simple issues:
- exclude the transitive dependency to jdk.tools in bookkeeer-benchmarks
- fix a warning due to the fact the Class.forName in java9 is deprecated and we are running javac with the "Werror" option (warning = error)

we have a real stopper, in fact we want to access the low level ID of FileDescriptors using the reflaction and by default this is not allowed.

This is the error:
