-----------------------------------
> More stable MathTransform.Inverse serialization
> -----------------------------------------------
>
> Key: SIS-410
> URL: https://issues.apache.org/jira/browse/SIS-410
> Project: Spatial Information Systems
> Issue Type: New Feature
> Components: Referencing
> Affects Versions: 0.5, 0.6, 0.7, 0.8
> Reporter: Martin Desruisseaux
> Assignee: Martin Desruisseaux
> Priority: Minor
> Fix For: 1.0
>
>
> The {{AbstractMathTransform.Inverse}} class is non-static. This cause the
> compiler to generate a {{this$0}} private field. But this synthetic fields
> may not be the same across implementations of different Java compilers.
> Consequently reading a class serialized with an Apache SIS library compiled
> with a different compiler may not recognize the fields that are named
> differently (see
> http://developer.java.sun.com/developer/bugParade/bugs/4211550.html). We
> should use static inner class with a named field (e.g. {{"forward"}})instead.
> This is an incompatible change, but {{AbstractMathTransform.Inverse}} is
> protected rather than public.
> In the particular case of {{AbstractMathTransform.Inverse}}, it also avoid a
> minor strangeness. Since we extends {{Inverse}} in different classes, we saw
> the synthetic {{this$0}} field duplicated in each subclass. Using a named
> field instead will avoid that.
