Description of problem:
When EAP starts, reference of MANIFEST.MF file which is under tmp directory remains in JVM. It will be cleared by GC. However, if EAP shut down before GC, it is not deleted from tmp file.

Version-Release number of selected component (if applicable):
EAP 6.2 Beta
Windows

How reproducible:
Always in windows environment

Steps to Reproduce:
1. Run EAP 6 server in windows environment.
2. Deploy a ejb-in-ear which is EAP 6 quickstart application.
3. Shutdown EAP 6 server.
4. You can confirm that MANIFEST.MF file remains under the tmp file.
ex)
standalone
  `-- tmp
       `-- vfs
             `-- deployment
                  `-- deploymentc1e1858a72ea8d31
                       `-- jboss-ejb-in-ear-web.war-6cc33f11c748d380
                            `-- META-INF
                                 `-- MANIFEST.MF

Additional info:
Its MANIFEST.MF InputStream is read/closed using readManifest() method in VFSUtils class. However, its InputStream is PaddedManifestStream[2]. I think it has to close a realStream object in PaddedManifestStream too when PaddedManifestStream is closed.
