Subject [jira] [Commented] (CASSANDRA-9608) Support Java 9
Date Wed, 07 Sep 2016 00:11:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-9608?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15469029#comment-15469029
] 

Dave Brosius commented on CASSANDRA-9608:
-----------------------------------------

Build fails with

Unable to load a script engine manager (org.apache.bsf.BSFManager or javax.script.ScriptEngineManager)

Adding jars bsf.jar, commons-logging.jar and rhino.jar to the ant class path (~/.ant/lib)
 fixes the problem, however because there are <script> and <scriptdef> tags at
the top most level in the build.xml, these jars can't be loaded as part of the build, and
work.

> Support Java 9
> --------------
>
>                 Key: CASSANDRA-9608
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9608
>             Project: Cassandra
>          Issue Type: Task
>            Reporter: Robert Stupp
>            Priority: Minor
>
> This ticket is intended to group all issues found to support Java 9 in the future.
> From what I've found out so far:
> * Maven dependency {{com.sun:tools:jar:0}} via cobertura cannot be resolved. It can be
easily solved using this patch:
> {code}
> -        <dependency groupId="net.sourceforge.cobertura" artifactId="cobertura"/>
> +        <dependency groupId="net.sourceforge.cobertura" artifactId="cobertura">
> +          <exclusion groupId="com.sun" artifactId="tools"/>
> +        </dependency>
> {code}
> * Another issue is that {{sun.misc.Unsafe}} no longer contains the methods {{monitorEnter}}
+ {{monitorExit}}. These methods are used by {{o.a.c.utils.concurrent.Locks}} which is only
used by {{o.a.c.db.AtomicBTreeColumns}}.
> I don't mind to start working on this yet since Java 9 is in a too early development
phase.
