vfs30 does not play well with 3rd party registering URLHandlers
---------------------------------------------------------------

                 Key: JBVFS-144
                 URL: https://jira.jboss.org/jira/browse/JBVFS-144
             Project: JBoss VFS
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 3.0.0.CR3
            Reporter: Thomas Diesler
            Assignee: John Bailey


The Felix OSGi Framework registers URLHandlers

http://svn.apache.org/repos/asf/felix/releases/org.apache.felix.framework-2.0.4/src/main/java/org/apache/felix/framework/URLHandlers.java

If it does so all access to file resources breaks and you should see 

14:00:38,361 INFO  [FelixIntegration] JBossOSGi Felix - 2.0.2.SP1-SNAPSHOT

14:02:05,411 WARN  [JBossEntityResolver] Cannot load systemId from resource: xml.xsd

Later there are also various classloading issues.

The URLHandlers can be disabled like this

        <entry><key>felix.service.urlhandlers</key><value>false</value></entry>

However then, you'll see a variation of [JBVFS-142]
