When selecting "open in Read-Only mode" for a path (in the GUI), it appears that its not being opened read only

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Choose your path
2. Select "Open in Read-Only mode"
3. Run an app performing indexing on the directory you will be opening from 
step #1
4. When the app is indexing, click "OK" from the GUI.
5. Receive the exception (from my app):  
"org.apache.lucene.util.SetOnce$AlreadySetException: The object cannot be set 
twice!"

What is the expected output? What do you see instead?

Luke should open in read-only mode.

What version of the product are you using? On what operating system?

RHEL 6.x, Like v3.5.0


Please provide any additional information below.

If I run command line using "java -jar ukeall-3.5.0.jar -ro -index [path to 
index]" this works fine and is opened read-only, no exceptions raised.  Please 
note, [path to index] is really my path to index (for example 
/home/sfloess/foo).
