Hi Georg,
Which version of Java are you using? Java 9 and later seem to have
tossed the the javax.imageio classes into the java.desktop package(1).
Cheers,
Jim

I am specifically referring to the ext part of imageio which as far as
I know is unsupported.
Which RT jar are you referring to? Indeed I mean the javaX class.

Are you sure it’s not javax.imageio.ImageIO which is included in
the rt.jar?
It’s possible that the class being loaded is somehow referencing
the wrong class (java vs javax). Perhaps a pluging specification
(META-INF) file is wrong?
https://docs.oracle.com/javase/8/docs/api/javax/imageio/ImageIO.html
is the current javadoc for the very much supported
javax.imageio.ImageIO class.
Note:
If you’re deploying on some older versions of JBOSS, there is a
sun JDK module defined in the modules folder which calls for
various packages to be imported from the JDK. By default these
older application servers will not load imageio from the JDK, and
you have to add imageio to the list of packages imported to make
this work.

*Subject:* [Geotools-gt2-users] no class found for
java.imageio.ImageIO
Hi,
I want to read a GridCoverage2D from an ESRi ArcGrid File using
geo tools on centos using openjdk 8.
But I get the error of
NoClassDefFoundError Could not initialize class java.imageio.ImageIO
Are there any viable solutions? If I understand the problem
correctly, imageio-ext does not bundle this class, instead it is
provided as an extension to the SUN / Oracle JDK (which has ceased
to be maintained for years).
Desired state:
Read ArcGrid Files, and then use a PolygonExtractionProcess.
Are there possibilities to not require the missing Class?
Best,
Georg
