Hello, the plugin crashes whenever I start the IDE, this is the error:

Is it related to Java version or what can it be ?

I have the same problem. IDEA 14.0.3 @ ubuntu 14.04; java 6

[ArthurianX]

I tried with JAVA 6,7,8 and it is exactly the same.

@casser - do you have any idea what could be causing this ?

Guys this should be Java Version Issue, I have compiled plugin using Java 7, so if you IDE runtime is less then 7, this will cause problem, @ArthurianX which version of IDE you have and which platform ?
