JDK 1.4.2 (native) KQUEUE descriptor leak?

[Nick Sayer]

I'm running a fairly sophisticated application that uses JMS and the 
java mail framework as well as connecting to a bunch of databases.

The JDK was built with the 1.4 port (a while ago, when the machine was 
still running 5.2.1), and the machine is running 5.3.

Using 'lsof,' I'm seeing a leak of KQUEUE type file descriptors.

Does this ring a bell for anyone?
