Description

Getting this error:

java.lang.IncompatibleClassChangeError: Class co.e.Outer does not implement the requested interface org.slf4j.Logger
	at co.e.Outer$Inner.myMethod(Outer.groovy:19)
	at co.e.Outer.doSomething(Outer.groovy:13)
	at co.e.Outer$doSomething.call(Unknown Source)

when running the following code:

package co.e

@CompileStatic
@Slf4j
class Outer {

  void run() {
    def m = [:]
    log.info(m.toString())
    new Inner().myMethod(m)
  }

  @Slf4j
  private class Inner {
    void myMethod(Map m) {
      log.info(m.toString()) // fails here
    }
  }
}

It runs fine if I remove the @CompileStatic
