--------------------------------------------

             Summary: AccessControlException while loding FST models in the Lucene FST Linking engine
                 Key: STANBOL-1177
                 URL: https://issues.apache.org/jira/browse/STANBOL-1177
             Project: Stanbol
          Issue Type: Bug
          Components: Enhancement Engines
            Reporter: Rupert Westenthaler
            Assignee: Rupert Westenthaler


As reported by Andreas Kuckartz the FST linking engine may encounter 

java.security.AccessControlException: access denied
("java.io.FilePermission"
"{..}/stanbol/integration-tests/target/launchdir/stanbol/indexes/default/dbpedia-2013.10.09/data/fst/dbpedia_ont_surfaceForm.en.fst"
"read")
at java.security.AccessControlContext.checkPermission(AccessControlContext.java:372)
at java.security.AccessController.checkPermission(AccessController.java:559)

at org.apache.stanbol.enhancer.engines.lucenefstlinking.TaggingSession.obtainFstCorpus(TaggingSession.java:334)

NOTE that this is not reproduceable on all environments. 

Engines need to use AccessController.doPrivileged(..) for File IO
