Two wars using second level cache

[scottg]

I'm trying to deploy two webapps, both with infinispan configured as the hibernate second level cache, but on startup I recieve the following exception.

Caused by: org.infinispan.config.ConfigurationException: Detected interceptor of type [org.hibernate.cache.infinispan.impl.ClassLoaderAwareCache$ClassLoaderAwareCommandInterceptor] being added to the interceptor chain more than once!

The relevant configuration in both persistence.xml files is is this.

<property name="hibernate.cache.region.factory_class"

                 value="org.hibernate.cache.infinispan.JndiInfinispanRegionFactory"/>

<property name="hibernate.cache.infinispan.cachemanager"

                 value="java:jboss/infinispan/hibernate"/>

<property name="hibernate.transaction.manager_lookup_class"

                 value="org.hibernate.transaction.JBossTransactionManagerLookup"/>

<property name="hibernate.cache.use_second_level_cache" value="true"/>

<property name="hibernate.cache.use_query_cache" value="true"/>

<property name="hibernate.cache.use_minimal_puts" value="true"/>

Any ideas?

Could you include the full exception stack trace?

I was able to recreate with a unit test.  Exception call stack is shown here http://pastebin.com/gi4VxRgg

Scott,

Can you create a jira for this issue?  That way, you can get credit for finding this bug. 

Thanks for reporting it!

Here is a quick hack.  Please still create a bug report in jira (https://issues.jboss.org/browse/AS7) for this.  Or let me know if you won't and I will.

Add a unique cache manager in each application:

App1:

<property name="hibernate.cache.infinispan.cachemanager"

                 value="java:jboss/infinispan/hibernate_App1"/>

App2:

<property name="hibernate.cache.infinispan.cachemanager"

                 value="java:jboss/infinispan/hibernate_App2"/>

The default cache manager name "java:jboss/infinispan/hibernate" is already configured in AS/standalone/configuration/standalone.xml.  You need to add new caches for "java:jboss/infinispan/hibernate_App1" and "java:jboss/infinispan/hibernate_App2"

Change standalone.xml from:

{quote}

<subsystem xmlns="urn:jboss:domain:infinispan:1.0" default-cache-container="hibernate">

<cache-container name="hibernate" default-cache="local-query">

<local-cache name="entity">

<eviction strategy="LRU" max-entries="10000"/>

<expiration max-idle="100000"/>

</local-cache>

<local-cache name="local-query">

<eviction strategy="LRU" max-entries="10000"/>

<expiration max-idle="100000"/>

</local-cache>

<local-cache name="timestamps">

<eviction strategy="NONE"/>

</local-cache>

</cache-container>

</subsystem>

{quote}

Change to:

{quote}

<subsystem xmlns="urn:jboss:domain:infinispan:1.0" default-cache-container="hibernate">

<cache-container name="hibernate" default-cache="local-query">

<local-cache name="entity">

<eviction strategy="LRU" max-entries="10000"/>

<expiration max-idle="100000"/>

</local-cache>

<local-cache name="local-query">

<eviction strategy="LRU" max-entries="10000"/>

<expiration max-idle="100000"/>

</local-cache>

<local-cache name="timestamps">

<eviction strategy="NONE"/>

</local-cache>

</cache-container>

<cache-container name="hibernate_App1" default-cache="local-query">

<local-cache name="entity">

<eviction strategy="LRU" max-entries="10000"/>

<expiration max-idle="100000"/>

</local-cache>

<local-cache name="local-query">

<eviction strategy="LRU" max-entries="10000"/>

<expiration max-idle="100000"/>

</local-cache>

<local-cache name="timestamps">

<eviction strategy="NONE"/>

</local-cache>

</cache-container>

<cache-container name="hibernate_App2" default-cache="local-query">

<local-cache name="entity">

<eviction strategy="LRU" max-entries="10000"/>

<expiration max-idle="100000"/>

</local-cache>

<local-cache name="local-query">

<eviction strategy="LRU" max-entries="10000"/>

<expiration max-idle="100000"/>

</local-cache>

<local-cache name="timestamps">

<eviction strategy="NONE"/>

</local-cache>

</cache-container>

</subsystem>

I have been trying a to add a bug report, but when I try to log into Jira I get internal server error.

[smarlow]

I just tried to login and was able to.  Perhaps if you tried again, it might work better now.

[scottg]

Still no go, I sent a support request yesterday but have not heard anything. Perhaps you should go ahead and set up the issue.

[smarlow]

I created jira AS7-1544 for this issue.  Thanks again for reporting it.  Let me know if the above workaround helps you.

[smarlow]

Actually, a better workaround (set PU property "hibernate.cache.region_prefix" to a unique value) is described in the jira.  The above workaround is not as good.

[smarlow]

Fixed for AS 7.0.1! 

[scottg]

Very quick turn around. Thank you.
