[jira] [Created] (OPENJPA-2977) convert() mutates caller config, ignores mappingFiles

Maxim Solodovnik created OPENJPA-2977:
-----------------------------------------

             Summary: convert() mutates caller config, ignores mappingFiles
                 Key: OPENJPA-2977
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2977
             Project: OpenJPA
          Issue Type: Sub-task
          Components: jpa
    Affects Versions: 4.2.0
            Reporter: Maxim Solodovnik
             Fix For: 4.2.0


Discussion thread: https://github.com/apache/openjpa/pull/144#discussion_r3683004644


**(medium)** `convert(PersistenceConfiguration)` mutates the caller's configuration object (`config.property(...)` for MetaDataFactory and noPersistenceXMLResource) - a surprising side effect for a converter, and repeated `createEntityManagerFactory(config)` calls keep appending. It also ignores `config.mappingFiles()` and `config.qualifiers()` entirely, and `setPersistenceUnitName(config.name())` is called twice (lines 648 and 662). Could the OpenJPA-specific properties go into the returned map instead, and mapping files be wired through?
