[010620_1]

If servlet was created under some directory structure and then other 
directory from this structure is mounted, moving servlet throws exception.

How to reproduce:

1. Suppose you have directory "first" and in this directory you have directory 
"second". 
2. Mount directory "second".
3. Create in this new mounted directory new servlet form template. It will look 
like this:

  first
    +--- second (-> mount point)
           +---- servlet.java

4. Unmount this filesystem and mount directory "first". In this directory create 
new directory, e.g. third. Now it will look like this:

  first (-> mount point)
    +--- second 
    |      +---- servlet.java
    +--- third

5. Cut "second" directory and paste it under "third" directory. 
Following exception is thrown. If you delete .nbattr before moving then 
exception isn't thown.
