We do this downstream in SapMachine though, so worst thing you could just take over your patch for Coretto too (see https://github.com/SAP/SapMachine/blob/d574d26282fd2e67aa242de176bbe6cdc1e41205/src/hotspot/share/prims/jvm.cpp#L2920).

HeapDumpOnOutOfMemoryError won't react  OOME thrown from Java libraries.  [JDK-8257790](https://bugs.openjdk.java.net/browse/JDK-8257790).  eg. `java.nio.ByteBuffer.allocateDirect(size)` may throw OOME just like thread exhaustion.
