Description

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] is true. The pcStateManager however does not have the flag ACC_SYNTHETIC set:

$ javap -verbose MyEntity.class
[...]
  protected transient org.apache.openjpa.enhance.StateManager pcStateManager;
    descriptor: Lorg/apache/openjpa/enhance/StateManager;
    flags: ACC_PROTECTED, ACC_TRANSIENT
[...]

According to the JVM Specs

[...]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.[...]

Is this flag intentionally not set?
