I don't know what kinds of things you're doing on the JVM, but the only situations where I've seen these kinds of errors were either a) batch jobs on massive amounts of data (which yeah... it figures that they could OOM, not sure how you'd prevent that), or b) a serious error in application logic. In general, I don't really encounter these problems and neither do most other people who write for the JVM.
