Murmur hash implementation in Java

This is a Java implementation of the Murmur hash 2.0, a relatively fast hash function for architectures with efficient multiplication. Both 32bit and 64bit version are implemented with corresponding jUnit tests. The interface is straightforward:

public final class MurmurHash {
    public static int  hash32( final byte[] data, int length);
    public static long hash64( final byte[] data, int length);
    public static int  hash32( final byte[] data, int length, int seed);
    public static long hash64( final byte[] data, int length, int seed);
    public static int  hash32( final String text);
    public static long hash64( final String text);
    public static int  hash32( final String text, int from, int length);
    public static long hash64( final String text, int from, int length);
}
