-------------------------------------------------------------------
[~julianhyde] Ok, I will make pull request with this change and add
documentation to the ProjectionTransformer. Regarding release process, should
the notice be added to the site/develop/index.md file?
[~desruisseaux] Recently, I tried to avoid using reflection, due to the
complications it introduces when using GraalVM and ahead-of-time compilation.
From what I understand, Calcite extensively rely on reflection, so this
shouldn't be a problem. However, even if the classloader work around works
well, I think it makes developpers hesitant to adopt the geoapi standard.

> As explained by [~desruisseaux] in [1], despite being released with an Apache

> by Proj4j come with restrictive terms of use [2] and we should find an
> alternative.
