jhsdb: Open a core dump in interactive debug mode.

jhsdb

$ jhsdb clhsdb --core ${path-to-core_dump} --exe ${path-to-jdk-bin-java}

try on your machine

The command "jhsdb clhsdb" is used to run the clhsdb tool provided by Java HotSpot Debugger (JHSDB). This tool is specifically designed for analyzing core dumps generated by the Java Virtual Machine (JVM) during crashes or abnormal terminations.

The "--core ${path-to-core_dump}" parameter specifies the path to the core dump file that you want to analyze. The core dump file contains a snapshot of the JVM's memory at the time of the crash.

The "--exe ${path-to-jdk-bin-java}" parameter specifies the path to the Java runtime executable (java) of the JDK you want to use for analysis. This is the binary file used to execute Java programs.

So, by executing the given command, you are running the clhsdb tool to analyze a specific core dump file (${path-to-core_dump}) using a specific JDK executable (${path-to-jdk-bin-java}). This allows you to inspect the JVM's memory and potentially troubleshoot the cause of the crash.
