JBoss Warns about "ISPN000163: FileCacheStore ignored an unexpected file in path"

Solution Verified - Updated

Environment

  • JBoss Enterprise Application Platform (EAP) 6.0.0, 6.0.1
    • Infinispan

Issue

  • JBoss frequently throws the following WARN message:
WARN  [org.infinispan.loaders.file.FileCacheStore] (OOB-18,null) ISPN000163: FileCacheStore ignored an unexpected file in path /jboss-eap-6.0/standalone/data/infinispan/web/default-host. The store path should be dedicated!

Resolution

  • Apply EAP 6.4 CP14 when available which fixes the This content is not included.BZ1412495 when using nested contexts a/b, a/c,. Note: you will need to remove the folders if they already exist prior to applying CP14 patch.

  • As a work around, you can bind your application to the root context instead through one of the following methods, which appears to provide a proper store path:

    • Deploy your application as ROOT.war
    • Bind your application to the root context in the jboss-web.xml like so instead:
<context-root>ROOT</context-root>

Root Cause

  • This was previously fixed by AS7-4283, but a regression from AS7-4612 reintroduced this bug.
  • This now appears to occur specifically when an application is deployed and bound to the root context through its WEB-INF/jboss-web.xml like so:
<context-root>/</context-root>
