Paul King commented on GROOVY-7970:
-----------------------------------
I think it probably should - but I'll work on that more tomorrow and see if any
ugly cases come up. It is always tricky with closures since they are so
flexible, you can't make as many assumptions about what they would definitely
produce. The type checking extension mechanism is in place for that purpose. If
we can't be certain what should happen we should leave it out of the main
compilation path.

> Key: GROOVY-7970
> URL: https://issues.apache.org/jira/browse/GROOVY-7970
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.7
> Reporter: Graeme Rocher
>
> This example:
> {code}
> 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
> {code}
> Results in a compilation error:
> {code}
> [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
> {code}
> If you attempt to use {{Bar.this}}:
> {code}
> Writable writable = Bar.this.renderTemplate((Object)o, arguments)
> {code}
> The result is a VerifierError
> {code}
> java.lang.VerifyError: (class: Bar$1$_writeTo_closure1, method: doCall
> signature: (Ljava/lang/Object;)Ljava/lang/Object;) Incompatible argument to
> function
> at Bar$1.writeTo(ConsoleScript11:15)
> at groovy.lang.Writable$writeTo.call(Unknown Source)
> at
> org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48)
> at
> org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:113)
