-------------------------------------------------------------------
Key: JBCACHE-1601
URL: https://issues.jboss.org/browse/JBCACHE-1601
Project: JBoss Cache
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Cache loaders
Affects Versions: 3.2.5.GA
Reporter: Dennis Reed
Assignee: Dennis Reed
When cache.getNode loads a passivated node, the data is not loaded, but it does trigger an
eviction event.
When eviction then passivates the node again, the data is overwritten.
Similar to JBCACHE-825.

CacheFactory factory = new DefaultCacheFactory();
Cache cache = factory.createCache("cache.xml");
cache.put ( fqn, "test", "data" );
Thread.sleep ( 3000 ); // wait for eviction
cache.getNode ( fqn );
Thread.sleep ( 3000 ); // wait for eviction
System.out.println ( cache.get ( fqn, "test" ) );
Expected result: "test"

Dennis Reed commented on JBCACHE-1601:
--------------------------------------
org.jboss.cache.interceptors.CacheLoaderInterceptor
loadIfNeeded(bypassLoadingData=true) creates a node in memory, but does not load the
data
PassivationInterceptor doesn't check to see if the data is loaded:
node.isDataLoaded()
This affects both CacheLoaderInterceptor/PassivationInterceptor and
LegacyCacheLoaderInterceptor/LegacyPassivationInterceptor.
It also affects getChildrenNames (the only other call that sets bypassLoadingData=true).
