Fixed possible infinite loop in random of RandomStringUtils Hi, I faced that the `random` method can cause an infinite loop. It can be caused if the **end** parameter is too low for generating either numbers (< 48) or letters (<65). I added some exception tests to make the cases clear. Basically, if we call the random function with for example `numbers = true && end < 48 ` the validation for `Character.isDigit(ch)` will fail and we increment count `count++`. Moreover: - Removed the white spaces in RandomStringUtilsTest.java - Added the terms (inclusive) (exclusive) to the Javadoc of the random method to make it more clear.
