The CmpJpaConversion.mapFields() method uses a list called the "ENHANCEED_FIELDS" to mark a number of fields as transient. Some of these certainly make a lot of sense, such as "serialVersionUID" and "class$Ljava$lang$String". I am curious about the different "pc*" fields. I've not found any reference to these in the OPENEJB code. Are these fields something that would be generated by JPA? Are they OpenJPA specific, or something that any JPA implementation would be using? I'm particularly curious if this is something that would need to change if support for additional JPA engines (e.g., EclipseLink) were to be added.
When OpenJPA enhances classes, it adds "pc*" fields, and I found that sometimes our generation code would see these fields and get confused. The pc* hack seemed to make the problem go away, and I never got back to looking at the problem in depth. It is possible we would need additional hacks for eclipse link; I just don't know for sure.
