This is a complete showstopper for World Singles. As I commented in
This breaks code that uses the Java String.startsWith() member function - the two argument version:
We just tried to update to 4.2.0.008 at World Singles and this is a complete showstopper. Adobe did something equally stupid in CF11 by adding a .replace() member function that overrode String.replace() and broke existing code (in FW/1). This addition of an incompatible .startsWith() / .endsWith() member function pair is equally stupid. Please revert this change as soon as possible.
Why on earth add member functions that conflict with Java methods in a way that CHANGES THE FUNCTIONALITY IN A SUBTLE way??
