-----------------------------------------
Does this fix also resolve [GROOVY-7373]?
> Builders don't work in Traits
> -----------------------------
>
> Key: GROOVY-7456
> URL: https://issues.apache.org/jira/browse/GROOVY-7456
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.3
> Reporter: Graeme Rocher
> Assignee: Cédric Champeau
> Fix For: 2.4.4
>
>
> Traits don't take into account closure delegates, this completely breaks any
> builder or dynamic behaviour. The following example:
> {code}
> import groovy.xml.*
> trait MyBuilder {
> def build2() {
> def mkp = new MarkupBuilder()
>
> mkp.foo {
> bar()
> }
> }
> }
> class Foo implements MyBuilder {
> def build1() {
> def mkp = new MarkupBuilder()
>
> mkp.foo {
> bar()
> }
> }
> }
> foo = new Foo()
> foo.build1()
> foo.build2()
> {code}
> Fails with:
> {code}
> roovy.lang.MissingMethodException: No signature of method: Foo.bar() is
> applicable for argument types: () values: []
> Possible solutions: wait(), any(), wait(long), use([Ljava.lang.Object;),
> any(groovy.lang.Closure), is(java.lang.Object)
