>                 Key: GROOVY-8327
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8327
>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 2.6.0-alpha-1, 3.0.0-alpha-3, 2.5.2
>         Environment: groovc command line on linux
>            Reporter: Isaac Dooley
>            Priority: Major
>
> The parser in 2.6.0-alpha-1 gives a MultipleCompilationErrorsException on code that compiled
successfully in 2.4.12. 
> {code:title=Code that fails to compile on 2.6.0-alpha-1}
> class A {
>     static String g() { }
>     A() {
>         this({g()}) // It is ok to create a closure that calls g() in a constructor,
but not if it is being passed into this().
>     }
>     A(a) { }
> }
> {code}
> {code:title=compilation error message}
> $ groovyc test.groovy  
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> test.groovy: 4: Can't access instance method 'g' before the class is constructed
>  @ line 4, column 15.
>            this({g()}) // It is ok to create a closure that calls g() in a constructor,
but not if it is being passed into this().
>                  ^
> 1 error
> {code}
> My opinion is that groovy should allow users to call a static method inside a constructor
before the instance has been fully constructed, but I'm not aware of the details of why this
is disallowed in 2.6.0-alpha-1.
