Release Note: Added isEmpty Default Method to CharSequence - Closed
Description
Adding isEmpty as a default method on CharSequence would harmonize String with other CharSequence implementations.

isEmpty was added to String in Java 1.6, but at the time there was no means to add it to the CharSequence interface without breaking compatibility.

Implementations of CharSequence in the JDK should be examined to see if they would benefit from providing an override of the new isEmpty() default method. (This can be done in this changeset or in a follow-up changeset, as appropriate.) There should be tests added for the default methods as well as for any overriding methods.
