It's not the fault of the JVM runtime nor the the language per se since both are excellent. The blame should instead be placed on the political process within Sun, which has created a lag in getting a decent IO event model/system available in the form of an API.
This newer system is suppose to be able to scale to tens of thousands of FDs and be able to handle heavy duty server side stuff in a more graceful manner. It's a reasonable system from what I saw, but the implementation of it is highly OS dependent and will be subject to those environmental constraints. Couple this and the HotSpot compiler (supposeablly competitive with gcc's -O3 from benchmarks) and it should be high useable for a broad range of of server side work when intelligently engineered.
