Description

This example:

import groovy.json.*
import groovy.transform.*

@CompileStatic
class Bar {
    private Writable renderTemplate(Object o, Map args) {
    
    }
    def foo(Map map, Map arguments) {
    
        def writable = new Writable() {
            @Override
            Writer writeTo(Writer out) throws IOException {
                StreamingJsonBuilder builder = new StreamingJsonBuilder(out)
                builder.call {
                    for(key in map.keySet()) {
                        def o = map.get(key)
                        Writable writable = renderTemplate((Object)o, arguments)
                        call(key.toString(), writable)
                    }
                }
                return out
            }
        }
    }
}

writable = new Bar().foo([one:'two'],[foo:'bar'])

sw = new StringWriter()
writable.writeTo(sw)
println sw

Results in a compilation error:

[Static type checking] - Cannot find matching method Bar$1#renderTemplate(java.lang.Object, java.util.Map). Please check if the declared type is right and if the method exists.
 at line: 18, column: 45

If you attempt to use Bar.this:

Writable writable = Bar.this.renderTemplate((Object)o, arguments)

The result is a VerifierError

java.lang.VerifyError: (class: Bar$1$_writeTo_closure1, method: doCall signature: (Ljava/lang/Object;)Ljava/lang/Object;) Incompatible argument to function
	at Bar$1.writeTo(ConsoleScript11:15)
