<p>we are working on an application which uses geotk in the
version 3.20. Whilst there is no problem using OpenJDK 8 to
start the application, Java 11 gives us the follwing stack
trace:</p>

<p>Is there any work around this with geotk 3.20?</p>

<p>I'm not aware of a way that would not require modification of
source code. The current code uses the JDK class <tt>javax.imageio.spi.ServiceRegistry</tt>
for managing factories. That class was compatible with <tt>java.util.ServiceLoader</tt>
but with more functionalities (in particular the capability to set
precedence between factories). But since Jigsaw in Java 9, <tt>java.util.ServiceLoader</tt>
has evolved to become the only "official" mechanism for managing
services in a modularized world. The JDK added a restriction on <tt>javax.imageio.spi.ServiceRegistry</tt>
presumably for inciting developers to migrate to <tt>java.util.ServiceLoader</tt>.</p>
<p>The fix is to replace all our use of <tt>javax.imageio.spi.ServiceRegistry</tt>
by <tt>java.util.ServiceLoader</tt> in source code. We have not
done yet this work. Alternatively, can you share which Geotk
functionalities you use? If those functionalities are available in
Apache SIS, the migration may possibly be mostly a matter of
changing package names.</p>
