    Description

      The patch for JDK-6563143 has introduced a warning for overriding equals without hashCode, this fix has to be made more precise, such as warning if equals is overridden and hasCode is Objects.hashCode rather than requiring hashCode to be overriden in the same type.

      Also add source info to the warnings.
