Java HotSpot VM Command-Line HeapDumpPath option use hostname for resulting .hprof

Summary: Id like to alter the way .hprofs are named when automatically created to incorporate machine’s hostname + process PID

Long version: According to documentation ( you can pass an option to the VM to create heapdumps under certain conditions (HeapDumpOnOutOfMemoryError), and can further customize this behavior by specifying a different path for the resulting .hprof file.

Could it be done? Can HeapDumpPath accept a parameter to get the hostname?
