Ryan McGuire created CASSANDRA-6749:
---------------------------------------
Summary: -Dcassandra.boot_without_jna=true does not actually
disable JNA
Key: CASSANDRA-6749
URL: https://issues.apache.org/jira/browse/CASSANDRA-6749
Project: Cassandra
Issue Type: Bug
Reporter: Ryan McGuire
Priority: Minor
The JVM argument '-Dcassandra.boot_without_jna=true' appropriately allows
Cassandra to start if the jna jar file *is missing* from the lib directory.
However, in the case that the jar *does* exist, this flag does not actually
disable JNA.
I am basing this assertion on the fact that even when I use this flag I see my
entire heap space is preallocated (mlockall.) and by restarting after removing
the jna jar file, the heapspace is not preallocated.
