Hi, I am getting problems while configure my treecache-service.xml with
EvictionPolicy and CacheLoader in JBossCache 1.2 (on a JBoss 4.0.1 server).
I've got the following message:
Starting failed jboss.cache:service=TreeCache
org.jboss.util.NestedRuntimeException: - nested throwable:
(java.lang.NullPointerException)
......
Caused by: java.lang.NullPointerException
at org.jboss.cache.eviction.LRUPolicy.nodeVisited(LRUPolicy.java:100)
This is my service.xml:
<?xml version="1.0" encoding="UTF-8"?>
|
| <server>
|
| <classpath codebase="./lib" archives="jboss-cache.jar, jgroups.jar"/>
|
| <mbean code="org.jboss.cache.TreeCache"

| <region name="/_default_">
| <attribute name="maxNodes">5000</attribute>
| <attribute name="timeToIdleSeconds">1000</attribute>
| </region>
| </config>
| </attribute>
|
| <attribute
name="CacheLoaderClass">org.jboss.cache.loader.FileCacheLoader</attribute>
| <attribute name="CacheLoaderConfig">
| location=C:/tmp</attribute>
| <attribute name="CacheLoaderShared">false</attribute>
| <attribute name="CacheLoaderPreload">/</attribute>
| <attribute name="CacheLoaderFetchTransientState">false</attribute>
| <attribute name="CacheLoaderFetchPersistentState">true</attribute>
| </mbean>
| </server>

The problem dissapear when I don't Preload any node with CacheLoader.
