Jetty 6.1.2 (rc2) don't do multi core processor

Recently we upgraded our work laptop to Intel dual core processor.

After moving my local working code branch to new pc, I start to see some very strange things happened. In some tests where the web server issues an httpClient call to itself hangs indefinitely. No time out; no response, the thread is just suspended.

In comparison, the very same code runs merrily on my old pc (single core), I can see the httpClient request invokes a new thread on itself.

Adding the mystery, the problem on dual core pc is intermittent- in about 20% occasion it starts a new thread.

Jetty doesn't spawn a new thread on multi core CPU. Looking back I can come to this conclusion but the process to get to here wasn’t easy. Then I google out this bug report

I quickly upgrading to Jetty 1.6.3 - the stable build just released, the problem've gone away.
