Programmatically dumping the Java heap

[kjkoster]

Dear All,

Here is a neat snip of code to programmatically create a heap dump from a JVM. This is useful if you want to trigger a heap dump at precisely the right place in your code, or if creating a heap dump from an external program is impractical.

Basically, the code retrieves the Sun-specific HotSpot JMX bean and calls the heap dump method on that mbean. Simple and powerful.
