Manually reset the networkaddress.cache.ttl value to the defaults (Fixes #1268)

When searching for the networkaddress.cache.* values java will default to these
values when it can't find a manually set value, however if a security manager is
in place then as a special case java will set the cache lifetime to infinite.
Manually setting the values solves this issue.
