Lucene Directory race condition on segments iterator has NPE thrown by Lucene index opening
-------------------------------------------------------------------------------------------

                 Key: ISPN-498
                 URL: https://jira.jboss.org/browse/ISPN-498
             Project: Infinispan
          Issue Type: Bug
          Components: Lucene Directory
    Affects Versions: 4.1.0.BETA2, 4.1.0.BETA1, 4.1.0.ALPHA3, 4.1.0.ALPHA2, 4.1.0.ALPHA1, 4.0.0.Final
            Reporter: Sanne Grinovero
            Assignee: Sanne Grinovero
             Fix For: 4.1.0.CR1, 5.0.0.BETA1


{code}
Set<String> filesList = getFileList();
return filesList.toArray(new String[filesList.size()]);{code}
is wrong as the size() allocates an array of a size which is potentially bigger than the number of Strings it's going to contain, populating some null values in the resulting array (which angers Lucene quite a lot)
