Re: [Geotools-gt2-users] GeoTools 34.0 released for Java 17 with Eclipse ImageN processing engine

[Andrea A. <and...@ge...>]

Hi,
I second what Jody said, there was no plan to make the coexist, it's an
upgrade path.
However... I believe that a coexistence could be possible, the java packages
are different, so by having ImageN use a different file name for the
registry files in META-INF,
from registryFile.jai to registryFile.imagen, a coexistence might be
possible, even if likely
wasteful (two separate image processing caches in memory are not the
greatest of ideas).

A coexistence is just not in our plans, but since ImageN is not yet
available as 1.0, if DWD wants
to put the development effort to get it done, I would not be against it.
I see this applicable to the GeoServer 3.0 series.

I would recommend switching existing software to ImageN though, we prepared
migration scripts
that should help in the endeavor.

Regards,

Andrea Aime
