> I'm using reflection to do various things on an entity-class during my unit tests. Because my tests are not interested in any of OpenJPAs internals, I'm trying to skip any field generated during enhancement. Basically I skip every field with where [Field#isSynthetic|https://docs.oracle.com/javase/8/docs/api/java/lang/reflect/Field.html#isSynthetic--]] is true. The pcStateManager however does not have the flag ACC_SYNTHETIC set:
> {code:java}
> $ javap -verbose MyEntity.class
> [...]
> protected transient org.apache.openjpa.enhance.StateManager pcStateManager;
> descriptor: Lorg/apache/openjpa/enhance/StateManager;
> flags: ACC_PROTECTED, ACC_TRANSIENT
> [...]
> {code}
> According to the [JVM Specs|https://docs.oracle.com/javase/specs/jvms/se8/html/jvms-4.html#jvms-4.7.8]
> {quote}[...]A class member that does not appear in the source code must be marked using a Synthetic attribute, or else it must have its ACC_SYNTHETIC flag set.[...]
> {quote}
> Is this flag intentionally not set?
