The test can be triggered to fail reliably using -Dseed=-5185871966573548947 as an argument to jtreg (although that failure is for the Boyer Moore ASCII section).

EVALUATION Looks like the algorithm is wrong: we create a random pattern, a random string which does not contain that pattern and expect that after insertion of that pattern into string the new string will match our pattern only once, at the insertion point (well, at least not earlier) Counterexample to that: pattern 'abab', string 'abcd', insert in the middle
