A typical call to `new SecureRandom()` is slowed down by looking for a constructor in NativePRNG which takes `java.security.SecureRandomParameters`. NativePRNG does not have such a constructor, so the search fails, incurring all the cost of the lookup and creating a subsequent exception.

Creating a dummy constructor which takes and ignores this parameter will speed up `new SecureRandom()` calls significantly.
