A DESCRIPTION OF THE PROBLEM :
"Invalid" indices - that is, indices that I didn't add - are returned by getSelectedIndices() depending on the order setModel and addListSelectionListener are executed.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Compile and run the program below - the output is 0|1, even though the only index that was selected is 0.
2. Comment out the first line with setModel; uncomment the second line with setModel, compile and run the program again - the output is 0|

EXPECTED VERSUS ACTUAL BEHAVIOR :
The output should be the same (preferably 0|) in both cases.

REPRODUCIBILITY :
This bug can be reproduced always.
