#276 Static Error: No method in static JavacCompiler has name 'ru
During the middle of a Dr. Java session, my colleague began receiving the message "Static Error: No method in static JavacCompiler has name 'runCommand'" whenever she tried to run a program (even a simple "Hell World" program). We don't believe there were any configuration changes to Dr. Java or the JDK. Does anyone know what causes this?
We need to know a little bit more about your system to help you. Please start DrJava, click on the "Help" menu, and select the "About" menu item. In the dialog that opens, please click the "Copy System Properties" button. This will put some information into your clipboard. Please paste that information here in a new comment.
Thanks,
The DrJava Team
Here is our system information. I also pasted in the System Properties. Thanks!

Thanks for the system information. Unfortunately, I'm stumped.
You said she began receiving the message during a DrJava session, i.e. it worked before?
If this re-occurs, perhaps you could try one of our more recent weekly releases, e.g. this one:
