Joaquin Casares resolved CASSANDRA-4104.
----------------------------------------
Resolution: Not A Problem
With cassandra -f printing out the error, this is acceptable behavior.
> Cassandra appears to hang when JNA enabled and heapsize > free memory
> ---------------------------------------------------------------------
>
> Key: CASSANDRA-4104
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4104
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.0.8
> Reporter: Joaquin Casares
> Priority: Minor
> Labels: datastax_qa
>
> When JNA is enabled heapsize is larger than free memory, all that is printed
> out is the classpath, then the printouts stop.
> If you hit enter again, you get the commandline, but no Cassandra process is
> running.
> Tested on both OpenJDK and Oracle Java.
