How to change javac display language to english?

Question

I am using Windows 8 with Japanese. I installed the SE8 JDK, and the javac compiler messages are all in Japanese.

I tried changing the non-Unicode language system setting to English, restarting and reinstalling the JDK, as suggested in similar questions, but now javac just displays a bunch of question marks on the command line. How to change the output to English?

Answer 1

Try passing this argument: -J-Duser.language=en . See This post: Passing "-J-Duser.language" to javac via ant to ensure that compilation errors are reported in the correct language
