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

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
