groovy 7909 bug

> on trait declaration order
> -------------------------------------------------------------------------------------------------------
>
> Key: GROOVY-7909
> URL: https://issues.apache.org/jira/browse/GROOVY-7909
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.4.7
> Environment: Grails 3.1.9
> Reporter: Sébastien Collin
> Priority: Critical
>
> I'm using trait for multiple inheritance and I faced an issue when compiling
> my project (using Grails 3.1.9, so with the gradle task CompileGroovy).
> My traits are sharing a common method ({{def method()}}) and I'm referencing
> parent's version through ParentClassName.super.method()
> I'm seeing this error:
> {quote}
> > BUG! exception in phase 'semantic analysis' in source unit 'xxx.groovy'
> > ClassNode#getTypeClass for YYY is called before the type class is set
> {quote}
> When testing different cases it seems that this problem appears because
> classes are not compiled in the right order.
> For example, a script with
> {code}
> trait Three implements One, Two {
> def postMake() {
> One.super.postMake()
> Two.super.postMake()
> println "Three"
> }
> }
> trait One {
> def postMake() { println "One"}
> }
> trait Two {
> def postMake() { println "Two"}
> }
> class Four implements Three {
> def make() {
> Three.super.postMake()
> println "All done?"
> }
> }
> Four f = new Four()
> f.make()
> {code}
> will fail, whereas putting Three method after One and Two will succeed.
> Beside, keeping this trait's declaration order but changing method names to
> be unique (and removing {{XXX.super}}) will compile and execute correctly.
> I hope I'm clear enough...
