That's your option of course, but I can't imagine why.
The problems of the Java garbage collector are widely discussed and
there has been research on fixing it for years, a lot of that done by
IBM. The early 1.0 and 1.1 Java GCs were particularly bad, fragmenting
severely and frequently failing to deallocate unreferenced objects.
If I observe a Java program leaking memory, it has to be the libraries
(classes) if it isn't the garbage collector. Well, it could be the JVM
itself I suppose, but I'd think that is less likely than the GC or the
If you'll spend 15 minutes with Google, you'll find quite a bit of
information on problems with Java garbage collection, both in how the GC
works, and how people (mis)use it.
I run Java 1.4.1 right now, the Sun distribution for Linux x86.
It's possible the default setup is just bad, but I can't usually run
more than one Java application at a time.
One thing interesting about 1.4.1 is the introduction of parallel
garbage collectors for SMP systems. I'm wondering if it would help a
really fast uniprocessor system too. Might make the application run
smoother since the GC would not have to stop the world when doing a GC
