Provider org.geotools.referencing.factory.epsg.CartesianAuthorityFactory could not be instantiated

Question

I'm using the maven-shade-plugin to package GeoTools packages into my uber Jar:

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.2.2</version>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
                <configuration>
                    <transformers>
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                            <mainClass>this.is.my.MainClass</mainClass>
                        </transformer>
                    </transformers>
                    <shadedArtifactAttached>false</shadedArtifactAttached>
                    <shadedClassifierName>launcher</shadedClassifierName>
                </configuration>
            </execution>
        </executions>
    </plugin>

The service works when the JAR is built and run in a docker-compose environment, but when I run the service in Netbeans I get several exceptions:

And so on.

My pom contains:

The code being executed is:

sourceCRS = CRS.decode("EPSG:4326");

Edit: I forgot to say that I'm running Fedora 31 running OpenJDK 11. Netbeans is configured to use OpenJDK 1.8 as the default platform. This may be a problem due to class loaders?

Any ideas what I'm doing wrong? Thanks

You need to provide an actual implementation of the referencing code. From the FAQ:

Q: How to choose an EPSG Authority?

The referencing module does not do very much out of the box - it needs someone to tell it what all the funny codes mean (such as “EPSG:4326”).

You need to choose a single EPSG jar to have on your classpath; if you have several EPSG jars on your classpath you will get a FactoryException.

For most needs just use the gt-epsg-hsql plugin:

• gt-epsgh-hsql: will unpack an HSQL database containing the official EPSG database into a temp directory, a great solution for desktop applications.

There are several alternatives:

• gt-epsg-wkt: uses an internal property file and is lightweight rather than official and correct. A great solution for applets

• gt-epsg-postgres: uses the official EPSG database which you have to load into PostgreSQL yourself. A great solution for Java EE applications.

• gt-epsg-access: directly use an the official EPSG database as distributed. A great solution for windows users that need the latest official database.

Unsupported:

• gt-epsg-oracle: Load the official EPSG database into oracle to use this plugin

• gt-epsgh-h2: use this popular pure java database
