Grails: "Method may be static" inspection shown wrongfully

***What steps will reproduce the issue?***
1\. Create a Grails project that has a class with a non static method that could be static with the exception of having a non static logger. See screenshot for example code.
***What is the expected result?***

Inspection is not triggered-

***What happens instead?***

Inspection "Method may be static" is shown. If building example we get the error "46: Apparent variable 'log' was found in a static scope but doesn't refer to a local variable, static field or class." See screenshot for code.

Also, the IDE should show the above case as a compile error (static method with non-static content) since the software does not compile.

Start by reproducing the issue in a Grails project with a non-static method and a non-static logger, focusing on the "Method may be static" inspection. Done means the inspection is not shown for this case and the IDE reports the resulting static-scope compile error.
