What version of JRE do you use to run IDEA with? You can check it by clicking Help -> About.

IDEA versions prior to 14 come bundled with a JDK6; i guess the released plugin is compiled against JDK8, hence the class incompatibility. You can change the JVM version in Info.plist (see https://devnet.jetbrains.com/docs/DOC-197), but this is not advised by Jetbrains and may have unwanted effects (change in display f.i.)
