    Description

      Drools should not allow set two rules with the same name for the same package

      As expected, Drools does not allow us to define two rules with the same name in a same DRL file.
      But if there are two rules with the same name, in the same package, but in separate files, no exception or warning is issued, just one rule overrides the other in silence.

      From documentation:
      "A rule must have a name, unique within its rule package. If a rule is defined twice in a single DRL, an error will appear when one loads it. If a DRL that includes a rule name already in the package is added, the previous rule is repalced."[1]

      [1] http://docs.redhat.com/docs/en-US/JBoss_Enterprise_SOA_Platform/5/html/JBoss_Rules_5_Reference_Guide/chap-language_reference.html#sect-rule

      Different behavior for a similar action is not good. Both should alert user about a rule name repeated.
      For large projects using a lot of DRL files can be hard to track mistakes occurred by rules override . It is really necessary provide an ERROR message for this.
