      Add the following to SymlinkTestCase.java:

      SymlinkTestCase.java
         public void testJarFileScheme() throws Exception
   {   
      URL url = getResource("/vfs/test/level1.zip");
      try 
      {   
        VFS vfs = VFS.getVFS(new URL("jar:file:" + url.getPath() + "!/" + "level2.zip/level3.zip"));
      }   
      catch(NullPointerException npe)
      {   
        failure("NPE thrown because jar:file: not handled by canonicalization code.", npe);
      }

      Add the following to SymlinkTestCase.java: SymlinkTestCase.java public void testJarFileScheme() throws Exception { URL url = getResource( "/vfs/test/level1.zip" ); try { VFS vfs = VFS.getVFS( new URL( "jar:file:" + url.getPath() + "!/" + "level2.zip/level3.zip" )); } catch (NullPointerException npe) { failure( "NPE thrown because jar:file: not handled by canonicalization code." , npe); } }

      Accessing a jar:file: URL causes an NPE if -Djboss.vfs.forceCanonical=true

      Add the following to SymlinkTestCase.java:

      SymlinkTestCase.java
         public void testJarFileScheme() throws Exception
   {   
      URL url = getResource("/vfs/test/level1.zip");
      try 
      {   
        VFS vfs = VFS.getVFS(new URL("jar:file:" + url.getPath() + "!/" + "level2.zip/level3.zip"));
      }   
      catch(NullPointerException npe)
      {   
        failure("NPE thrown because jar:file: not handled by canonicalization code.", npe);
      }   
   }

      Results in:
