Does adding enumerators into Java enum break ABI?

Question

For example, in my code there is

public enum Color { RED, BLACK }

and I add a color later, that is

public enum Color { RED, BLACK, BLUE }

will this break ABI? That is, does my user need to recompile his Java classes?

13.4.26. Evolution of Enums

Adding or reordering constants in an enum will not break compatibility with pre-existing binaries.

Note that even reordering keeps compatibility, unlike in C/C++/C#.
