Test improvement: Convert Embedded GlassFish Maven Plugin Tests to use the latest plugin version

[OndroMih]

All the tests in https://github.com/eclipse-ee4j/glassfish/tree/6cab4ce3aad9bc65b52bc761a4aa88634a2bd0aa/appserver/tests/embedded/maven-plugin directory use the old maven plugin version 5.

Convert them to use the latest 8.0 version of the plugin: https://github.com/eclipse-ee4j/glassfish-maven-embedded-plugin

1. The new version uses a different artifactId: embedded-glassfish-maven-plugin instead of the old maven-embedded-glassfish-plugin(the groupId is the same)

2. The new version runs Embedded GlassFish in a separate JVM by default. It's OK to keep the default for most of the tests but it would be good to disable this mode for at least one test so that we test it too. For example, the simple test case, or the applicationDispatcher test case. To disable it, set in the plugin config:

<configuration>
    <fork>false</fork>
</configuration>

3. It's possible to remove the dependencies from the plugin definition in the maven-plugin/pom.xml file and just define the configuration property <version>${project.version}</version>. The plugin will know how to use the glassfish-embedded-all artifact with that version

Hi! I’d like to work on this issue if nobody else is currently assigned to it.

[OndroMih]

Sure, feel free to do it. Nobody is assigned to it. I can’t assign the task to you in GitHub because you’re not a committer but consider it assigned to you.

Thank you!

Hi @SavioFerreira ! How is work on the task progressing? I think that this issue is quite good for Claude. I could ask Claude to complete the task.
