Persistence extension does not work with Jacoco extension

When the Jacoco and persistence extension is used together in a project, a "PersistenceExtensionInitializationException: Unable to create persistence configuration" is thrown.

The cause of the exception is that in the ConfigurationImporter class the createConfiguration method receives a fieldsWithValues map with a "$jacocoData" item in it. Because the method cannot process this item, it fails.
