Thank you for your report.

The integers are parsed in this manner: 1) Use of built-in Java methods to attempt to parse the index (given as string) to an integer. Reference: parseInt() method

2) Check that the integer is unsigned non-zero.

For very large positive integers resulting in overflows, step 1) fails, which is a limitation of Java itself.
