Object.wait() inaccurate?

[class acts]

I'm noticing similar behavior to issue Java/94223 in diablo-jdk15 (
http://www.freebsd.org/cgi/query-pr.cgi?pr=94223)

I have a java.util.Timer task that executes every second but executes every
15ms - 1015ms.  I do have jdk15p2 installed on the same machine, but I have
confirmed via `ps` that my application is in fact using the diablo jdk.
same issue occurs on jdk15 p2 on the same box, but goes away if i try
linux-sun-jdk14.

machine is FreeBSD/i386 5.4 SMP dual Xeon EM64T


Kind Regards,
