How to disable minidump (mdmp) files generation with Java Hotspot JVM on Windows

Question

Currently I have a deployed executable jar file that creates large (7+ Gb) minidump files when it crashes. I would like to have a text representation of what caused the crash, not a binary file of the JVM state. I've tried using the information found in this CodeRanch post and the documentation that I've found in the Java documentation doesn't seem to help.

I also referenced this question but there's no definitive answer.

Is there a typical way this is done that I'm not aware of?

Take care that -XXdumpSize:none is the JRockit specific option you may quickly find when googling about this question. Hotspot JVM is not JRockit. – Airboat

FYI: Here's a mapping table for JRockit JVM and HotSpot JVM options: docs.oracle.com/javacomponents/jrockit-hotspot/migration-guide/… -- Some of the dump options unfortunately only appear in the JRockit JVM column. – Matthia

Answer 1

I found a command line option that seems to do what I want. Launching the jar with

java -XX:-CreateMinidumpOnCrash -jar myJar.jar

Seems to do the trick and will generate error logs that are very small compared to the minidumps.

Really difficult to find this option to prevent generation of Java JVM mdmp files on Windows system. – Airboat
