I was reading a book on programming skills wherein the author asks the interviewee, ‘How do you crash a JVM?’ I thought that you could do so by writing an infinite for-loop that would eventually use up all the memory.
Anybody has any idea?
The closest thing to a single ‘answer’ is
System.exit()which terminates the JVM immediately without proper cleanup. But apart from that, native code and resource exhaustion are the most likely answers. Alternatively you can go looking on Sun’s bug tracker for bugs in your version of the JVM, some of which allow for repeatable crash scenarios. We used to get semi-regular crashes when approaching the 4 Gb memory limit under the 32-bit versions (we generally use 64-bit now).
