org.waveprotocol.wave.model.testing.RandomProviderImpl
Implementation of RandomProvider for use in classes intended for use in GWT, which doesn't support java.util.Random. The implementation is simplistic and not well tested, so don't use it for any usage that depends on the quality of the generated pseudorandom numbers. The implementation is based on the recommendations in Knuth: The Art of Computer Programming, Volume 2, Section 3.6.
