Show a properties file message when using @Pattern?

Question

I'm using @Pattern to validate a field:

@Pattern(regexp = Patterns.ZIP_CODE, message="validation.ZIP_CODE")
private String zip;

In my messages.properties file I have this:

validation.ZIP_CODE=Must match NNNNN or NNNNN-NNNN

The javadocs seem to imply that it should look up the validation.ZIP_CODE message:

Returns:
The error message template.
Default:
"{javax.validation.constraints.Pattern.message}"

But instead I get the text:

validation.ZIP_CODE

Am I misunderstanding the javadoc, or am I implementing this incorrectly?

In order to use an internationalized message in a JEE 6 Pattern annotation, I believe you must wrap the property name in open/close curly braces.

@Pattern(regexp = Patterns.ZIP_CODE, message="{validation.ZIP_CODE}")
private String zip;
