> Description of problem:
> In org.infinispan.loaders.decorators.AsyncStoreConfig, the default flushLockTimeout is set to 5000. However, the default in the JBoss Infinispan schema ($JBOSS_HOME/docs/schema/jboss-as-infinispan_1_X.xsd) is set to 1. Because of this, if the thread-pool-size for write-behind is increased, then it is likely that one of the threads will not be able to obtain the state map lock within the 1 millisecond time provided by the schema default. This results in the following error:
> ERROR o.i.loaders.decorators.AsyncStore.run - ISPN000051: Unexpected error
> org.infinispan.CacheException: Unable to acquire lock on update map
>           at org.infinispan.loaders.decorators.AsyncStore.acquireLock(AsyncStore.java:293) ~[infinispan-core-5.1.3.FINAL.jar:5.1.3.FINAL]

> Version-Release number of selected component (if applicable):
> Infinispan version 5.1.8
> How reproducible:
> Code inspection
> Steps to Reproduce:
> 1. Check the default value for flush-lock-timeout in $JBOSS_HOME/docs/schema/jboss-as-infinispan_1_3.xsd
> 2. Check the default value for flushLockTimeout in the org.infinispan.loaders.decorators.AsyncStoreConfig class
> 3. Note the disparity
> Actual results:
> Default in schema is 1
> Expected results:
> Default in schema is 5000
