#1549 [HHQ-2032] Expire Java's DNS cache for the HQ Agent

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-2032
When resources that the agent is monitoring (via the host name) change IP addresses, the resource will appear unavailable in HQ even when it is up and working fine. The reason is because Java is caching the DNS entry and by default will NEVER expire it. The following article contains options for telling Java to periodically expire the cache. We should implement one of these options for the agent installation and document this.
