Hello!

I want to use JdbmCacheLoader in my configuration for a cache persistence. I have created simple config:

<?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">

    <loaders passivation="false" shared="false">

          <loader

                class="org.jboss.cache.loader.jdbm.JdbmCacheLoader"

                async="false"

                fetchPersistentState="true"

                ignoreModifications="false"

                purgeOnStartup="false">

            <properties>

                location=D:/cache/#data

            </properties>

        </loader>

    </loaders>  

</jbosscache>

But this isn't working:

1. After a first start of application I see two DB files created in the directory d:/cache/.

2. I don't use cache during application run: I just start it and stop immediately.

3. During a second start of application I see a lot of errors. JBoss cache can't read persistence database which were created during first start. Generic reason:

Caused by: jdbm.helper.WrappedRuntimeException: org.jboss.cache.loader.jdbm.JdbmFqnComparator

          at jdbm.helper.DefaultSerializer.deserialize(DefaultSerializer.java:99)

          at jdbm.recman.BaseRecordManager.fetch(BaseRecordManager.java:341)

          at jdbm.recman.CacheRecordManager.fetch(CacheRecordManager.java:263)

          at jdbm.recman.CacheRecordManager.fetch(CacheRecordManager.java:242)

          at jdbm.btree.BTree.load(BTree.java:276)

          at org.jboss.cache.loader.jdbm.JdbmCacheLoader.openDatabase(JdbmCacheLoader.java:186)

          at org.jboss.cache.loader.jdbm.JdbmCacheLoader.start(JdbmCacheLoader.java:157)

          at org.jboss.cache.loader.CacheLoaderManager.startCacheLoader(CacheLoaderManager.java:461)

4. If I change in my config file JdbmCacheLoader to FileCacheLoader then cache works fine.

Where is my error in the configuration? How to correctly use JdbmCacheLoader ?

Please help me by good advice

Best regards,
