Labels: class-generation trait traits (was: class-generation traits)

> --------------------------------------------------------------------------
>
> Key: GROOVY-7443
> URL: https://issues.apache.org/jira/browse/GROOVY-7443
> Project: Groovy
> Issue Type: Bug

>
> this fails:
> def aWithB = new ClassA().withTraits(traitB)
> when traitB is not from the classloader of class A.
> full example code:
> {code:Java}
> package groovy.lang.traits
> import org.codehaus.groovy.control.CompilerConfiguration;
> class GroovyTraitsClassloaderTest {
> static class ClassA {
>
> }
>
> static trait TraitA {
>
> def aMethod() {
> println "traitA method"
> }
>
> }
>
> static main(args) {
>
>
> def aWithA = new ClassA().withTraits(TraitA)
>
> aWithA.aMethod()
>
>
> GroovyClassLoader gcl = new
> GroovyClassLoader(Thread.currentThread().getContextClassLoader());
>
> Class classB = gcl.parseClass("""\
> class ClassB {}
> """)
>
> Class traitB = gcl.parseClass("""\
> trait TraitB {
>
> def bMethod() {
> println "traitB method"
> }
>
> }
> """)
>
> //ok
> def bWithA = classB.newInstance().withTraits(TraitA)
> //ok
> def bWithB = classB.newInstance().withTraits(traitB)
> bWithB.bMethod()
