Running Win 7 Pro 64x and Python 2.7 I get a few errors. 1) I had to add inspect to the import list. 2) The 1st value, [0], in the tuple is an empty string. The 2nd, [1], shows the file name. I am guessing that the first should be the path... Any ideas?

System.out.println(2147483647 + 1); // no error
By contrast a long literal would compile fine:
System.out.println(2147483648L); // no err...
