Analyzing HotSpot Crashes

Volker Simonis, Development Expert, SAP

Have you ever found hs_err_pid or replay_pid files in your Java application directory? Has your Java application ever crashed and you didn’t know why? This session unveils the contents stored by the HotSpot crash handler in the corresponding error files and how this information can be used to analyze and reproduce the crash. It also introduces tools such as the jcmd and the HotSpot Serviceability Agent, which helps introspect native core files and extract the relevant Java information that is otherwise not easily accessible by native debuggers. After this session, you’ll be able to easily detect, classify, and handle problems you encounter with your Java HotSpot VM.
