Dennis Reed updated JBCACHE-1601:
---------------------------------

    Steps to Reproduce: 
<?xml version="1.0" encoding="UTF-8"?>
<jbosscache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:jboss:jbosscache-core:config:3.2">
    <eviction wakeUpInterval="1000">
        <default algorithmClass="org.jboss.cache.eviction.LRUAlgorithm">
            <property name="timeToLive" value="1000" />
        </default>
    </eviction>
    <loaders passivation="true" shared="false">
        <loader class="org.jboss.cache.loader.FileCacheLoader" async="false" fetchPersistentState="true"
                        ignoreModifications="false">
            <properties>
                location=${java.io.tmpdir}/JBCACHE-1601
            </properties>
        </loader>
    </loaders>
</jbosscache>


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"
Actual result: "null"

> 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.
