Description

The parser in 2.5, 2.6, 3.0 gives a MultipleCompilationErrorsException on code that compiled successfully in 2.4

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) { }
}

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

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.
