> Activation of a passivated node can remove parents from cache loader
> --------------------------------------------------------------------
>
> Key: JBCACHE-1504
> URL: https://jira.jboss.org/jira/browse/JBCACHE-1504
> Project: JBoss Cache
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: Cache loaders, Eviction
> Affects Versions: 3.1.0.CR1
> Reporter: Krzysztof Sobolewski
> Assignee: Manik Surtani
> Attachments: ParentRemovedDuringActivationTest.java

> The test (attached) performs the following steps:
> 1a) put(/a/a/a, x, x)
> 1b) put(/a/a, x, x)
> 2) evict(/a, true)
> 3) put(/a/a/a, x, y)
> 3a) ActivationInterceptor removes /a/a/a from cache loader and parents (if also loaded)
> 4) test that get(/a/a, x) is not null fails
> The thing is that during step 3 the node (/a/a/a) gets loaded; this also needs to create its parent (/a/a) because it too was evicted. The parent is created empty (not loaded) but it has a flag DATA_LOADED set, so during the following step 3a its data gets removed too, because ActivationInterceptor thinks it's safe to do that.
