Class HeapDumper

java.lang.Object

org.springframework.integration.test.util.HeapDumper

public class HeapDumper
extends Object

Use to take a heap dump programmatically. Useful to examine the heap when debugging sporadic test failures.

Commented out because it uses access-restricted classes and some IDEs won't build the project without relaxing the access restriction.

Usage: HeapDumper.dumpHeap("/tmp/foo.hprof");

If the file exists already, it will be replaced.
