How to let java output English errors instead of other languages?

My system is Chinese, and when there is an error occurs in my java program, it may output non-English error messages which is unreadable:

Caused by: java.io.IOException: CreateProcess error=2, 系统脮也禄碌陆指露

or: 

IOException occured : Cannot run program "cmd /C tsc hello.ts": 
CreateProcess error=2, ϵͳÕҲ»µ½ָ¶

Is it possible to let java always output English error messages ?

There are two parts to the answer.

  1. Java displays error messages based on the default locale. There are three system properties which define the default locale: user.language, user.country and user.variant. If you have access to your Java VM command line you can set these properties using the -D command line switch. E.g. this is enough to switch Java to generic English:

    java -Duser.language=en com.my.Class

  2. You can define a JAVA_TOOL_OPTIONS environment variable and specify your options there. Any JVM starting in such environment will pick these options up as if they were on the command line.
