Hi Please help review the change for 7067045.
The change is to throw a more meaningful IAE instead of the StringIndexoutputOfBoundsException if backslash or $ is the last character in the replacement string. (as the API indicated, the backslash and $ character in String's regex replacement and Matcher class have special meanings, backslash is for literal character escape and the $ is the capturing group reference, which needs a group index).
