Possible Java 17 compatibility issue regarding it.geosolutions.imageio-ext dependencies

[copierrj]

A compatibility issue was discovered while using some deegree modules (version 3.6.0-pre1) as a dependency in a Java 17 project. The resulting stacktrace was very similar like the one reported here: geosolutions-it/imageio-ext#143

It is perhaps a good idea to create a dedicated unit test to verify runtime ImageIO behavior.
