Added some additional tests with a focus on affix matching, specifically ensuring SIOOBE does not leak out in any of those cases. i.e. The bounds checks should ensure `false` is returned for those cases. But specifically for the failing JCK test, the main test we need on the JDK repo side is a negative ParsePosition index test.
