We are using Infinispan 4.2.1 and facing some issue in parsing of infinispan config file with java 7. 
 
Here is xml element of our config which is causing issues.
 
{code}
 <!-- A query cache that replicates queries. Replication is asynchronous. -->
   <namedCache name="replicated-query">
      <clustering mode="replication">
         <async/>
      </clustering>
      <locking isolationLevel="READ_COMMITTED" concurrencyLevel="1000"
               lockAcquisitionTimeout="15000" useLockStriping="false"/>
      <!--Eviction configuration.  WakeupInterval defines how often the eviction thread runs, in milliseconds.  0 means
         the eviction thread will never run.  A separate executor is used for eviction in each cache. -->
      <eviction wakeUpInterval="5000" maxEntries="10000" strategy="LRU"/>
      <expiration maxIdle="100000"/>
      <!-- State transfer forces all replication calls to be synchronous,
           so for calls to remain async, use a cluster cache loader instead -->
      <loaders passivation="false" shared="false" preload="false">
         <loader class="org.infinispan.loaders.cluster.ClusterCacheLoader" fetchPersistentState="false"
                 ignoreModifications="false" purgeOnStartup="false">
            <properties>
               <property name="remoteCallTimeout" value="20000"/>
            </properties>
         </loader>
      </loaders>
   </namedCache> 
{code}

This configuration is working fine with java 6. Recently we moved to java 7 and  it started complaining for  {code} <properties> <property name="remoteCallTimeout" value="20000"/> </properties>  {code}
 
with the following error  message
 
{code}

Which says {code} properties is not valid {code} and expecting {code} typedProperties , singletonStore or async {code}
Important point to note here is that {code}typedProperties{code} is not part of [xsd |http://docs.jboss.org/infinispan/schemas/infinispan-config-4.2.xsd]
 
What I have tried so far
1. if I remove the {code}<properties>{code} element from the config, it loads the config.
2. if i try renaming {code}properties to typedProperties {code} as it is complaining in the error message, I get the following error saying {code}typedProperties  is invalid and properties  is expected.{code}

{code}
    [junit] Caused by: javax.xml.bind.UnmarshalException
    [junit]  - with linked exception:
    [junit] [org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 5478; cvc-complex-type.2.4.a: Invalid content was found starting with element 'typedProperties'. One of '{"urn:infinispan:config:4.2":async, "urn:infinispan:config:4.2":singletonStore, "urn:infinispan:config:4.2":properties}' is expected.]
 {code}
 
I could see following in source of infinispan in {code} AbstractCacheStoreConfig.java {code} this may be causing this. 
 
{code}
@XmlElement(name="properties")
   public TypedProperties getTypedProperties(){
      return properties;}
{code}
 
 Any guesses.
