Episode 53 “Analyzing Crashed JVMs” [IJN] – Inside.java

JEP 528 is a candidate OpenJDK enhancement that would extend the jcmd diagnostic tool to work on core dumps from crashed JVMs, enabling post-mortem analysis without a running JVM. Currently jcmd can retrieve heap dumps, thread dumps, GC insights, and virtual thread scheduler statistics only from live JVMs. Once adopted, the same information could be extracted from crash core dumps for easier debugging.
