Java: How to specify JVM argument -XX:ErrorFile and preserve automatic PID in filename

java jvm-arguments hs-err
edr picture edr · Mar 24, 2014 · Viewed 8.9k times · Source

I am using the JNI and when there is a crash due to errors in the target application a hs_err_pid*.log file is generated. I want to change the default location where that file is stored. Now, from searching around I understand this can be achieved using the JVM argument -XX:ErrorFile.

The documentation says that the default for this parameter is ./hs_err_pid<pid>.log

Now, when I override the default, how can I tell the JVM to still include the process id in the filename? I have obviously tried to literally put targetDir/hs_err_pid<pid>.log as a command line parameter, but this led to the whole argument being ignored (and the file being stored to the default location, i.e. the working directory). If I only say targetDir/hs_err_pid.log the file is stored where I want it, but does not get a process id appended to the filename.

Any suggestions would be appreciated.
