exception on build 5706 when using checkstyle

I am using the checkstyle plugin (JetStyle), and when I click on the "Run CheckStyle For this File" icon I get the following exception in IntelliJ:

Error during dispatching of java.awt.event.MouseEvent[MOUSE_RELEASED,(439,53),button=1,modifiers=Button1,clickCount=1] on dialog18
