Difficulty running grails tests in IntelliJ : Illegal use of nonvirtual function call

Question

Lately I've been trying to run my spock tests in IntelliJ (which used to work beautifully and had great debugging / specific test re-running on failure features) and in the past few months I've began getting the following error:

| Error Error executing script TestApp: 
 (class: com/company/MyServiceSpec, method: super$2$oldImpl signature:
 (Ljava/lang/Object;)Ljava/lang/Object;) 
 Illegal use of nonvirtual function call (Use --stacktrace to see the full trace)

It's a spock test that runs just fine from the command line, individually (by specifying the class) or in the entire test-app series. Virtually all of the spock and plain old Unit or Integration tests I have on this project give similar failures in IntelliJ.

I've tried twiddling with the run features of the test (having classpath on or off, running an individual method, a whole test class, or the entire test series) with no luck to remedying the situation. I've also done a grails clean and tried re-running them from IntelliJ : that looked as if it worked once and I was able to run the tests for a little while, but then quickly after doing some work the problem now persists.

I know this is a bit of a vague question, but has anyone seen similar failures and found a reliable remedy? I'm on Grails 2.1 and Spock 0.7, same problem in both IntelliJ 12 and 13

I managed to solve this problem adding the following env variable in my configuration:

   _JAVA_OPTIONS='-Xverify:none'
