New Revision: 814024
URL: http://svn.apache.org/viewvc?rev=814024&view=rev
Log:
Switch to volatile for status flag used by multiple
threads during cluster context startup.
Without volatile problems have been observed, where the
change by one thread was actually not seen by the other
thread.
Performance implications are neglectable, because the
variable is only used during context startup.
