Unhelpful error message when constraint blocks all configurations

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a Constraint such that isValid() always returns false for the given 
configurations.  Trivially: public boolean isValid(Map<String, Object> 
aConfiguration) { return false; }
2. Attach this constraint to a ParameterSpace.
3. Attach the ParameterSpace to a BatchTask with a report.
4. Run the BatchTask.

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

See the attached file dkprolab.log for example logging output.  The error 
message rather cryptically complains about a missing file.  Instead it would 
have been helpful for there to be some message that no configurations passed 
the constraint.


What version of the product are you using? On what operating system?
0.8.0 on GNU/Linux

Please provide any additional information below.

I will try producing and submitting a minimal example later.

Hm, I'm not sure if this is due to a problematic constraint. The folder the 
report is looking in for the METADATA.txt is 
"/home/miller/opt/dkpro/de.tudarmstadt.ukp.dkpro.lab/repository/METADATA.txt". 
This is the root repository folder. It should be looking in a context folder 
like 
"/home/miller/opt/dkpro/de.tudarmstadt.ukp.dkpro.lab/repository/XXXXX/METADATA.t
xt" where "XXXXX" is a context id.

I didn't try a test case yet, but I'd suspect a bug in the report.
