[JPA] [EclipseLink] - Spring filters various packages in JPA temp class loader, prevent weaving of any models in these packages [SPR-6040]

[spring-projects-issues]

James Sutherland opened SPR-6040 and commented

Spring's JPA integration provides a tempClassLoader in the SpringPersistenceUnitInfo class. This loader defines an exclude filter base on the JPA providers package and a few other packages.

The issue is in writing test for EclipseLink the package org.eclipse.persistence was used for the model classes, but this filter is excluding these classes, so weaving does not work with Spring in any EclipseLink tests or examples.

The filter is not required, and EclipseLink will work without it. Either remove the package from the EclipseLinkDialect, or don't set it in SpringPersistenceUnitInfo.

This is not really a bug since we designed Spring's EclipseLink support for use with application code, not with EclipseLink's own test suite. That said - we can nevertheless remove that package exclusion if EclipseLink keeps working fine then.
