we actually do that since JDK 9, [JEP 279](https://bugs.openjdk.java.net/browse/JDK-8075621) added the failure handler which runs many things including `jstack`, `gdb -ex thread apply all backtrace` (or its equivalent) to get java and native thread dumps and `kill -ABRT` to generate core files on timeouts. however b/c it's run concurrently to a timed out process, you don't always get the data. so I'm wondering what you meant.
