Java static import causing compile error. Probable compiler bug?

Question

This compiles fine in Eclipse JDT but not on 1.6.30 or 1.7.25:

package doh;

import static doh.Wtf.InnerClass.innerclassMethod;
import java.io.Serializable;

public class Wtf {

    static class InnerClass implements Serializable {   
        public static void innerclassMethod() {            
        }
    }
}

With javac I get the following compile error:

error: cannot find symbol
  static class InnerClass implements Serializable {     
symbol:   class Serializable
location: class Wtf

Commenting out the superfluous static import makes the code compile. So does reordering the import statements.

Curious, but what's the purpose of importing a method to the file where it's implemented? — kiheru

Compiles fine in 1.7.0_21, both Eclipse and javac, without that redundant static import. — m0skit0

@kiheru Without the static import, you would have to call the method: InnerClass.innerClassMethod();. With the static import, you can just use innerClassMethod();. So same reason as with any other static import statement. — assylias

I get the same compile error with jdk 1.7.25.

It seems to be a known bug (although the example given in the bug report uses an enum as the nested class but it is conceptually identical) and the proposed workarounds are the same as those you describe:

swap import statements

remove static import and use fully qualified name
