Hi
I am trying to run EclipseLink 4.0.3 JPA in an OSGI Environment
I use the EclipseLink 4.0.2 OSGi Bundles in Target Platform.
I create an OSGi bundle with Activator
I put the persistence.xml into the META-INF directory
I add Meta-Persistence: META-INF/persistence.xml to MANIFEST.MF of the Plugin-Project:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Plugin
Bundle-SymbolicName: ch.eugster.persistence.plugin
Bundle-Version: 1.0.0.qualifier
Bundle-Activator: ch.eugster.persistence.plugin.Activator
Bundle-ClassPath: lib/mysql-connector-j-9.0.0.jar,
 .
Require-Bundle: org.eclipse.core.runtime,
 jakarta.persistence-api;bundle-version="3.1.0",
 org.eclipse.persistence.asm.source;bundle-version="9.7.0",
 org.eclipse.persistence.core;bundle-version="4.0.3",
 org.eclipse.persistence.jpa;bundle-version="4.0.3",
 jakarta.validation.jakarta.validation-api;bundle-version="3.0.2"
Bundle-RequiredExecutionEnvironment: JavaSE-21
Automatic-Module-Name: ch.eugster.persistence.plugin
Bundle-ActivationPolicy: lazy
Meta-Persistence: META-INF/persistence.xml


The persistence.xml looks like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<persistence version="3.0"
	xmlns="https://jakarta.ee/xml/ns/persistence"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="https://jakarta.ee/xml/ns/persistence 
             https://jakarta.ee/xml/ns/persistence/persistence_3_0.xsd">

	<persistence-unit name="test">
		<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
		<properties>
			<property name="jakarta.persistence.jdbc.driver"
				value="com.mysql.cj.jdbc.Driver" />
			<property name="jakarta.persistence.jdbc.url"
				value="jdbc:mysql://localhost:3306/test" />
			<property name="jakarta.persistence.jdbc.user" value="test" />
			<property name="jakarta.persistence.jdbc.password"
				value="test" />
			<property
				name="jakarta.persistence.schema-generation.database.action"
				value="create" />
		</properties>
	</persistence-unit>
</persistence>


I add a schema "test" with all privileges for user test and password test in my local mysql database system
in the Activator.start method I add code:

		Map<String, Object> properties = new HashMap<String, Object>();
		properties.put("jakarta.persistence.provider", PersistenceProvider.class);
		properties.put("jakarta.persistence.jdbc.driver", Driver.class);
		properties.put("jakarta.persistence.jdbc.url", "jdbc:mysql://localhost:3306/test");
		properties.put("jakarta.persistence.jdbc.user", "test");
		properties.put("jakarta.persistence.jdbc.password", "test");
		EntityManagerFactory emf = Persistence.createEntityManagerFactory("test", properties);
		EntityManager em = emf.createEntityManager();
		em.close();
		emf.close();


(the persistence.xml I put for getting shure).

When running I get the stacktrace:

I do not understand, what I am doing wrong. Am I missing something? Any help is appreciated!
