Using tutorials

CrashAnalysis is very simple and user-friendly to use. Enter log as a parameter into java-jar CrashAnalysis-1.0-SNAPSHOT.jar ${hs_err_pid.log} by executing the jar command

Java-jar CrashAnalysis-1.0-SNAPSHOT.jar ${hs_err_pid.log}

The CrashAnalysis-1.0-SNAPSHOT.jar file is packaged in the above warehouse and can be downloaded and used directly. It is much easier to use than to read the hs_err_pid.log file.

By default, it is compiled with jdk 1.8. if your jdk version is too low, it is recommended that you download the code and compile the jar file yourself.

Diagnostic effect

After executing the above command, there will be a tab page of diagnostic information, which will tell us the results of the analysis. For example, the following report:

This is a problem with the interpreter, that is, jvm made a mistake in converting bytecode into machine code. There are many reasons for this, generally jdk bug can be changed to different jvm modes such as-XInt, pure interpretation mode is compiled in the run-time information, you can check who went wrong by excluding compiling these classes to try.
