Workflow failed because an error in NameResemblance class

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Launch SoMoX configuration for a given project using the Run 
configurations... dialogue
2. SoMoX will finish successfully 
3. Launch new SoMoX configuration for a given project (it can be the same 
project as in the first step)
4. SoMoX will fail reporting an error in the workflow

What is the expected output? What do you see instead?
SoMoX should not fail. 

The problem is caused by the NameResemblance class. There is nameResemblanceMap 
map object which is set to be unmodifiable, so when we run SoMoX for second 
time, the same map is used from the first Launching. Since the map is set to me 
unmodifiable it can not be used again. 


Temporary solution for the users is to restart Eclipse before Launching the 
second SoMoX.
