shouldDelegateOnRecursiveLoad

protected boolean shouldDelegateOnRecursiveLoad()

Allows a reentrant getValue() call, made while this holder is already loading, to delegate to the original EclipseLink holder instead of starting the same Jmix load again.

Keep this opt-in: it is needed for collection holders whose owner is managed. During the internal owner reload, EclipseLink may resolve the same owner instance from the persistence context and touch the same collection holder. For detached owners the reload uses another managed instance, so the original holder is not expected to re-enter.

Returns:

true only when delegating is needed to break same-holder recursion
