Description

When a static import brings in a method which conflicts with a method defined in a class' super class Java invokes the method from the super class but Groovy invokes the method from the static import.

src/main/java/com/demo/Utils.java

package com.demo;

public class Utils {
    
    public static String getValue() {
        return "Utils.getValue";
    }
}

src/main/java/com/demo/MyBaseClass.java

package com.demo;

public class MyBaseClass {
    
    public static String getValue() {
        return "MyBaseClass.getValue";
    }
}

src/main/java/com/demo/JavaSubClass.java

package com.demo;

import static com.demo.Utils.*;

public class JavaSubClass extends MyBaseClass {
    
    public String retrieveValue() {
        return getValue();
    }
}

src/main/groovy/com/demo/GroovySubClass.groovy

package com.demo

import static com.demo.Utils.*

class GroovySubClass extends MyBaseClass {
    
    String retrieveValue() {
        getValue()
    }
}

src/test/groovy/com/demo/ImportTests.groovy

package com.demo

class ImportTests extends GroovyTestCase {
    
    void testJava() {
        def subClass = new JavaSubClass()
        def result = subClass.retrieveValue()
        assertEquals 'MyBaseClass.getValue', result
    }
    
    void testGroovy() {
        def subClass = new GroovySubClass()
        def result = subClass.retrieveValue()
        assertEquals 'MyBaseClass.getValue', result
    }
}

The Java test passes but the Groovy test fails.

To run the code download the attached project (staticimport.zip) and run "./gradlew test".
