Description

I'm using regexp validation constraint to enable email validation, however since regular expresion may contain "," regexp parsing failing with exception

My regexp annotation:

@Validate("required,regexp=([A-Za-z0-9][._-]*)[A-Za-z0-9]@([A-Za-z0-9-]
.)+[A-Za-z]

{2,6}

")
public String getEmail()

{ return email; }

Exception is:

Caused by: java.util.regex.PatternSyntaxException: Unclosed counted closure near index 62
([A-Za-z0-9][._-]*)[A-Za-z0-9]@([A-Za-z0-9-]\.)+[A-Za-z]{2
