Matrix Toolkits for Java

I have been using Colt for a while, and thought it is pretty good. Today I just came across another numerical library that could be the best I have ever seen - MTJ. Native interface to BLAS and LAPACK, sparse matrix solvers, and distributed matrix computation are all packed in one library?! Are you kidding me?! For those who stick with C++, I found MTL. For C# users, I found Math.Net. But they certainly cannot compete with MTJ in terms of the features mentioned above. Java people are just extremely blessed!
