-XX:+HeapDumpOnOutOfMemoryError

YourKit ProfilerのChangeLogよりはけーん．

Automatically by JVM if application fails with java.lang.OutOfMemoryError. To switch this behaviour on, -XX:+HeapDumpOnOutOfMemoryError JVM option should be specified. This option is supported in Java 6 "Mustang" JVM, and will be backported to Java 5.0 update 7 and Java 1.4.2_12.

JDK1.4.2_12にもバックポートしてあるようなので，今度試してみよう．
→OutOfMemoryError looks a bit better!
