Description
System.setSecurityManager0 calls
  InetAddressCachePolicy.setIfNotSet(InetAddressCachePolicy.FOREVER);

This call is redundant since the default cache policy is already set to FOREVER if not set by the command-line property when InetAddressCachePolicy is loaded and initialized (done by the static initializer).

We can remove this call from System.setSecurityManager0() implementation.
