 <p>It appears this is a JDK bug and it looks like this could be fixed by updating your JDK, what version are you currently on?</p> <p>It looks like <a href="https://issues.apache.org/jira/browse/CASSANDRA-8220" rel="nofollow">CASSANDRA-8220</a> (C* 2.2.1+, and 3.0.0-alpha1) was introduced to work around the problem, but I think upgrading your JDK should fix this as well.</p>
