Java: Regex not matching

I have comma separated string values. Every string may contain characters or numbers along with '-' or '/' or '.'.

My code looks like:

final String VALUES_REGEX = "^\\{([0-9a-zA-Z\\-\\_\\.])+,*([0-9a-zA-Z\\-\\_\\.])*\\}$";
final Pattern REGEX_PATTERN = Pattern.compile(VALUES_REGEX);
final String values = "{df1_apx.fhh.irtrs.d.rrr, ffd1-afp.farr.d.rrr.asgd}";
final Matcher matcher = REGEX_PATTERN.matcher(values);
if (null != values && matcher.matches()) {
    // further logic
}
...
...

Here if condition always returns false value because regex match fails. I verified regex using regexper. It looks fine.

Can you please tell me what is wrong here?
