JSR 303 implementation gives ClassCastException

Question

I am using custom validation annotation using JSR 303 and I am getting below error. I follow the details in Validating a field in a field using the Hibernate Validator (JSR 303)

java.lang.ClassCastException: com.sun.proxy.$Proxy95 cannot be cast to com.my.validator.FieldMatch

Can anyone help me out?
