Description
In the first paragraph of the "AddressCache" section of net-properties.html it is stated that reverse lookup results are also cached.

The java.net.InetAddress class only caches forward lookup (name lookup) results. Reverse lookup (address lookup) results are not cached.

"java/net/doc-files/net-properties.html" should be updated to match the source code, and the description of "networkaddress.cache.ttl" and "networkaddress.cache.negative.ttl" provided in the same section.
