RH Bugzilla Integration commented on ISPN-3496:
-----------------------------------------------

dereed at redhat.com made a comment on [bug 1002931|https://bugzilla.redhat.com/show_bug.cgi?id=1002931]

This bug is from LegacyConfigurationAdaptor#adapt(org.infinispan.config.Configuration) -- a new method added in Infinispan 5.2.

The calls in this method to legacy.getClassLoader() return the wrong classloader.

   public ClassLoader getClassLoader() {
      if (cl != null)
         // The classloader has been set for this configuration
         return cl;
      else if (cl == null && globalConfiguration != null)
         // The classloader is not set for this configuration, and we have a global config
         return globalConfiguration.getClassLoader();
      else
         // Return the default CL
         return Thread.currentThread().getContextClassLoader();
   }

The correct classloader to use was set by AS in the GlobalConfiguration.

But at the point that DefaultCacheManager#defineCache calls LegacyConfigurationAdaptor#adapt, setGlobalConfiguration has not been called on the configuration object, so globalConfiguration is null, causing getClassLoader to incorrectly return the TCCL instead of the correct classloader.

(In 5.1 setGlobalConfiguration was called later on during wireCache, but is no longer called at all in 5.2+)

>          Issue Type: Bug
>    Affects Versions: 5.2.1.Final
>         Environment: EAP 6.1.0 and 6.1.1. This is a regression since EAP 6.0.1

>            Priority: Critical

> A WAR deployment containing its own infinispan (such as JDG helloworld quickstart) and also having persistence.xml with second level cache enabled fails to deploy on EAP 6.1 HA configuration (standalone-ha.xml or standalone-full-ha.xml)
> Version-Release number of selected component (if applicable):
> EAP 6.1.0, EAP 6.1.1.ER4.
> Note: This does not happen with EAP 6.0.1 so it's a regression.
> Steps to Reproduce:
> 1. Get JDG 6.1 helloworld-jdg quickstart (or see the attachment)
> 2. Add persistence.xml with 2lc, e.g.:
> {code}
> <?xml version="1.0" encoding="UTF-8"?>
> <persistence xmlns="http://java.sun.com/xml/ns/persistence" 
>              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>              xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" 
>              version="2.0">
>    <persistence-unit name="entityManager">
>       <jta-data-source>java:jboss/datasources/ExampleDS</jta-data-source>
>       <properties>
>          <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
>          <property name="hibernate.cache.use_second_level_cache" value="true"/>
>          <property name="hibernate.cache.use_query_cache" value="true"/>
>       </properties>
>    </persistence-unit>
> </persistence>
> {code}
> 3. deploy the helloworld-jdg on standalone-ha.xml or standalone-full-ha.xml configuration of EAP 6.1. 
> This happens also when standalone.xml file is used to start EAP.
> The resulting error:
> {code}
