Tried playing with version 1.2 and 1.3 In both 1.2& 1.3 this works: System.out.println("test= " + matchRegexp("12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890", "^.{0,250}$")); in 1.2 this return true.. in 1.3 it stalls : System.out.println("test= " + matchRegexp("12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "123456789012345678901234567890123456789012345678901", "^.{0,250}$")); in both versions this stalls : System.out.println("test= " + matchRegexp("12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "12345678901234567890123456789012345678901234567890" + "1234567890123456789012345678901234567890123456789012", "^.{0,250}$")); Making the regex ^.{0,15}$ returns false in both versions. Looks like the bigger the second value in the regex is the longer it takes, 250 stalls and I have to test 0,2000 ...
