------------------------------------------------------------
Actually I was going to suggest we discuss this on the mailing list too. It's
not a given that we want to follow Java but we want to have well-specified
behavior for all cases. I know we don't have test coverage for all cases and I
imagine that what is currently implemented hasn't changed in some places even
with changes to Java etc. If someone doesn't beat me to it, I'll try to
formulate an email over the next few days while I am waiting for the 2.4.11
VOTE to timeout! :-)

> 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.
