[jpa-dev] Optimistic Locking: How to suppress version increment for some

[Rainer Schamm <rainer@xxxxxxxxxxxxxxxxxxx>]

Hi all

I am currently using optimistic locking with a simple version column on calendar appointment entity:

...

   @Version
   private Integer version;

...

I would like to be able to skip the version increment for certain entity updates.

I tried this (which did not work):

...

ContactEvent ce = em.find(ContactEvent.class, contactEventId, LockModeType.NONE);

...

Then I found that this hibernate annotation could probably help me to suppress the version increment in some cases:

...

@OptimisticLock(excluded = true)

...

But I am using Payara and EclipseLink does not seem to support this feature.

Does anyone have an idea how to cleanly suppress a version increment for certain updates (maybe via listeners)?

If there is currently no clean way when, then can we add this kind of annotation (@OptimisticLock) to the jpa spec in future?

Regards

Rainer
