Description

The following code appears to show that final is being applied inconsistently. A final list can be amended but an object that manipulates a lsit that is final cannot. In the former case the final is being applied to the reference and in the later, it is being applied to the object.

 class Blah {
  def list = []
   public plus ( item ) {
     list += [ item ]
     return this
   }
}

class Foobar {
   final static blah = new Blah ( )
}

final x = []
x += [1]
println ( x )

Foobar.blah += 1
println ( Foobar.blah.list )
> groovy finalProblem.groovy
