SearchFactoryState should use concurrent Maps for incrementally updated metadata
--------------------------------------------------------------------------------

                 Key: HSEARCH-822
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-822
             Project: Hibernate Search
          Issue Type: Bug
          Components: engine
    Affects Versions: 3.4.0.Final
            Reporter: Sanne Grinovero
            Assignee: Sanne Grinovero
             Fix For: 4.0.0.Alpha1


I've experienced very sporadic failures of MutableFactoryTest, when trying again it won't be reproduced.
The Workspace goes in NPE on the single-line method
{code}org.hibernate.search.backend.Workspace.getDocumentBuilder(Class<T>){code}
So it seems it's receiving work for a new entity type while the document builder of it was not "deployed" yet.

Indeed these DocumentBuilders are stored in a non-concurrent HashMap, replacing the implementation with a CHM it's now running the tests in a loop without reporting the exception anymore.
