Hi Paul,
That's good news.

FYI -- there have been some Classloader memory leak problems on Java  
5. However, they seem to be fixed on recent Java 5 runtimes

I ran some tests on Geronimo 1.1.1 running on a Linux box with java  
version "1.5.0_10-b02". Things look good, there.

I do see Classloader memory leaks running the same Geronimo binaries  
on my Mac (java full version 1.5.0_06-64). The same G 1.1.1 binaries  
work fine on Linux and they don't have any problem when run on my Mac  
using java full version 1.4.2_09-239. So once Apple brings Java 5 up  
to date on Mac OS X, I'm hopeful that these problems will be  
resolved. I didn't see any obvious work-arounds from Sun's bug
