How can I suppress the creation of the hs_err_pid file?

We are running a java application under java 1.6.0_13. When it crashes it creates the normal hs_err_pid file. I don't want this file created even if the application crashes. Is there a way on the java command line to sup开发者_JAVA技巧press this? I am familiar with -XX:ErrorFile option. If I set this to an empty string will that suppress it?

If you are using a Unix/Linux system, try setting -XX:ErrorFile to /dev/null (or, if you are using Windows, try NUL).

With Oracle HotSpot (since 6b21) and OpenJDK, the -XX:+SuppressFatalErrorMessage option should be used for preventing creation of the hs_err_pid file.

Nowadays, using -XX:ErrorFile=/dev/null will actually not work as expected, since if the file path specified to ErrorFile exists, the JVM will not attempt to overwrite it and will fall back to the default hs_err_pid location (there's no special case handling for /dev/null).
