-----------------------------------

             Summary: OsgiClassLoader needs null check when iterating bundles
                 Key: ISPN-4679
                 URL: https://issues.jboss.org/browse/ISPN-4679
             Project: Infinispan
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Core
    Affects Versions: 7.0.0.Beta1
            Reporter: Niels Bertram
            Assignee: Dan Berindei
            Priority: Minor


{{org.infinispan.commons.util.OsgiClassLoader}} requires a null check when the bundle is retrieved from a WeakReference. 

{code:java}
for (WeakReference<Bundle> ref : bundles) {
   final Bundle bundle = ref.get();
   // BUG: we may not get a bundle back from the weak reference, eg. if uninstalled or deactivated
   if (bundle.getState() == Bundle.ACTIVE) {
      try {
         final Class clazz = bundle.loadClass(name);
         if (clazz != null) {
            classCache.put(name, clazz);
            return clazz;
         }
      } catch (Exception ignore) {
      }
   }
}
{code}

I am running 7.0.0.Beta1 on servicemix 5.1.1 and can't load this simple infinispan.xml:

{code:xml}
<infinispan xmlns="urn:infinispan:config:7.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="urn:infinispan:config:7.0 http://infinispan.org/schemas/infinispan-config-7.0.xsd">
	<cache-container default-cache="default" name="TestContainer">
		<jmx domain="TestDomain" mbean-server-lookup="org.infinispan.jmx.PerThreadMBeanServerLookup" duplicate-domains="true"/>
		<!-- definitions of the caches -->
		<local-cache name="default" statistics="false">
			<locking concurrency-level="100" acquire-timeout="1000"/>
			<transaction mode="NONE" complete-timeout="3123" reaper-interval="123"/>
		</local-cache>
	</cache-container>
</infinispan>
{code}
