Dmitry Khamitov created GROOVY-8164:
---------------------------------------
Summary: Groovy allows a Java class to inherit static methods from
its interface
Key: GROOVY-8164
URL: https://issues.apache.org/jira/browse/GROOVY-8164
Project: Groovy
Issue Type: Bug
Components: Compiler, Static compilation
Affects Versions: 2.4.7
Reporter: Dmitry Khamitov
In the following situation Java doesn't compile (as per JLS8 - 8.4.8
Inheritance, Overriding, and Hiding):
{code:java}
interface Foo {
static void foo() {
System.out.println("static void foo() called");
}
}
class Bar implements Foo { }
public class FooBarTest {
public static void main(String[] args) {
Bar.foo();
}
}
{code}
{code}
$ javac FooBarTest.java
FooBarTest.java:3: error: cannot find symbol
Bar.foo();
^
symbol: method foo()
location: class Bar
1 error
{code}
But Groovy does compile, both dynamic and @CompileStatic and we get {{static
void foo() called}} in the output
Just in case, here is a snippet from _JLS8_:
*8.4.8 Inheritance, Overriding, and Hiding*
A class C inherits from its direct superclass all concrete methods m (both
static and instance) of the superclass for which all of the following are true:
...
A class does not inherit static methods from its superinterfaces.
