title: Cassandra windows, won't start up
body: <p>Installed it, Datastax CE, at first came up, but OpsCenter said agent was not up, although it seemed to be running. </p>
  
  <p>So I reboot, hoping it might be happier. Opposite. Now Cassandra Service and Agent won't even start.</p>
  
  <p>Going into logs I see</p>
  
  <blockquote>
    <p>2015-07-28 16:12:47 Commons Daemon procrun stdout initialized
    Error occurred during initialization of VM
    java/lang/NoClassDefFoundError: java/lang/Object</p>
  </blockquote>
  
  <p>Any idea what else I have to do? I have JDK 1.8, Eclipse etc. Nothing else complains.</p>
  
  <p>Thanks</p>
