You can use a profiler to trace it. Check out the following threads:

Besides, I'd suggest you to switch to latest release of Java5 or latest
build of future Java6, which is available from www.java.net: there are
a lot of greate improvements in GC performance and ergonomics since
1.4.2 and even 1.5.0
