Description Tom Ware CLA 2008-05-14 09:11:12 EDT 
Isolated caches in EclipseLink can be used for several things.  The initial design was to enable VPD support for Oracle. As a result, the default setting makes the cache "completely isolated".  This means that objects outside the isolated cache cannot reference objects inside the isolated cache.

Another use for this setting is to simply avoid storing objects in the shared cache.  When using isolated caches in this way, it is desirable to be able to set it on an Enity-by-entity basis and have some Entities stored in the isolated cache and some stored in the shared cache.

We should add a cache setting that allows this scenario.  GlassFish bug 5012 provides and example of a user that needs this functionality.

Comment 4 Shaun Smith CLA 2010-03-05 15:02:03 EST 
I've renamed this bug to frame it in terms of JPA 2.0 requirements.  Fixing this bug will probably resolve the bug as originally stated.

EclipseLink's restrictions regarding relationships between shared cached and not shared cached (isolated) entities are applied to JPA 2.0 entities that are cacheable and not cachable.  The example below with throw a validation exception.  If both entities are cachable true or both false, there's no exception.

It should be possible to mix Cachable(true) with Cachable(false) entities.

Reproduction attached.

@Entity
@Cacheable(true)
public class Publisher implements Serializable {
    @OneToOne
    private Address address;
...
@Entity
@Cacheable(false)
public class Address implements Serializable {

Comment 9 Karen Butzke CLA 2010-12-06 16:02:01 EST 
Hi Gordon,
I have a couple of schema suggestions for you:

1. In bug 328937, Guy mentioned that the partitioning policies should not have been added to the deprecated mapping basic-map and basic-collection. The same should apply for non-cacheable.

2.The annotation is named NonCacheable so I think in the schema it should be 'non-cacheable' instead of 'noncacheable'. Either that or the annotation should be renamed to Noncacheable.
Comment 10 Gordon Yorke CLA 2011-01-18 09:48:36 EST 
The annotation has been renamed to Noncacheable
Comment 11 Gordon Yorke CLA 2011-01-18 09:50:22 EST 
This bug has been resolved through multiple commits.  This bug was resolved through the new Cache Isolation feature.
Comment 13 TIAGO C CLA 2014-02-24 12:14:58 EST 
I found a work around of this bug. I couldn't migrate to JPA 2 so i had to find an other solution.

In my case, i only needed to put the Many size on cache, because this collection is not updated frequently. I couldn't use L2 cache in this collecion because of this bug (since the Many size had a reference to the One side (@ManyToOne).

What i did was to remove the @ManyToOne annotation and i used a normal @Column. And i used the @JoinColumn in the @OneToMany size. I know JPA 1 is not obligated to implement Unidirectional One-to-Many association using a foreign key mapping, but seems that eclipselink 1 supports it.

Hope it helps.
