Ever any performance different between Java >> and >>> right shift operators?

Is there ever reason to think the >> (signed) and >>> (unsigned) right bit-shift operators in Java would perform differently? I can't detect any difference on my machine. This is purely an academic question; it's never going to be the bottleneck I'm sure. I know: it's best to write what you mean foremost; use >> for division by 2, for ...
