It does not seem to have broken anything since I can open the command dialog window (Ctrl+Alt+4) and also run commands. I'm using IDEA 14.0.3 and the Forge IntelliJ plugin 1.0.9.Final on Fedora 20 with Oracle Java 1.8.0_11. sun.awt.image.BufImgSurfaceData cannot be cast to sun.java2d.xr.XRSurfaceData
