Alright, below is my message. In the next mail I will attach my files.

Dear Dan, all,

I do not have skills to get the stack trace. The code hangs one, Eclipse
does not print me its stack trace because it does not terminate the
program. So I decided to make a small test.java file that you can easily
run.

This code has the main function that simply runs getItemList() method which
successfully executes getDataset() method (here please download
mushroom.dat dataset and set the full path into filePath string variable)
and the hangs on (the problem happens on a fourth columnValues.add() call).
After the dataset was taken into X array, the code simply goes through X
column by column and searches for different items in it.

If you uncomment IntSet columnValues = new IntOpenHashSet(); and
corresponding import headers then everything will work just fine (you will
also need to include hppc jar file (can not attach because mail manager
prevents)).

Please feel free to ask if anything unclear.
