-----------------------------------
Summary: Groovy calls wrong method if there is a static method on
an interface
Key: GROOVY-7879
URL: https://issues.apache.org/jira/browse/GROOVY-7879
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 2.4.7
Reporter: Stefan Wolf
If there is an interface having the static method {{foo}} and a class {{Impl}}
implementing this interface also having a static method {{foo}}, then calling
{{Impl.foo()}} calls the method on the interface. For an easy self contained
example have a look at
https://github.com/wolfs/groovy-static-interface-method-test/blob/master/src/test/groovy/StaticInterfaceTest.groovy.
This can yield class cast exceptions on Java 8 and from Java 9 build 125
onwards this yields
{code}
java.lang.IncompatibleClassChangeError: Method ... must be InterfaceMethodref
constant
{code}
This verification has been introduced here:
https://bugs.openjdk.java.net/browse/JDK-8145148.
