[jira] [Commented] (CASSANDRA-7573) Cassandra 2.0.9 with IBM Java 7 crashes during start up

["Jason Plurad (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-7573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14101072#comment-14101072 ] 

Jason Plurad commented on CASSANDRA-7573:
-----------------------------------------

You're correct, this isn't a Cassandra bug -- it's in lz4-java.
For anybody interested, a pull request is now available to fix lz4-java.
https://github.com/jpountz/lz4-java/pull/46

Once that's pulled into lz4-java, it would be great if Cassandra would pick it up.

Thanks.

> Cassandra crashes during start up when using IBM Java 7 and generates a core dump.
> A workaround is to avoid the JNI native compressor by changing LZ4Factory.fastestInstance() to LZ4Factory.fastestJavaInstance() in src/java/org/apache/cassandra/transport/FrameCompressor.java and
> src/java/org/apache/cassandra/io/compress/LZ4Compressor.java
> I opened up an issue against lz4-java also at https://github.com/jpountz/lz4-java/issues/42
