Strange. The patch is definitely applied and I tried building it
twice just to make sure. The second time it run and generated about
100 docs before failure.

Which JVM did you test it on? Do you run multiple concurrent
threads, or is it just a plain single-threaded iteration?
Sun 1.5.0_12 on Windows XP SP 2.
I tested on Apple JVM 1.4.2 and 1.5.0 on OS X 10.4. Both single- and
Heap remains stable here over hundreds of runs.
With multiple concurrent runs, my CPU usage easily reaches 180-190%
The test app is running in a single thread although I can configure
it to run more threads.
I should mention that my machine is a Quad Core :) I don't think
that should matter since the application is single threaded.
I'd indeed think so, but... Doesn't it become relevant due to the JVM
implementation (synchronized, WeakReference, garbage collection)?
It would be interesting if somebody could perform a similar test with
yet another JVM (or with the same JVM, but on Linux, or Vista).
