'==' & '!=' not working properly with globals
---------------------------------------------

                 Key: JBRULES-954
                 URL: http://jira.jboss.com/jira/browse/JBRULES-954
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions:  4.0.0.MR3
         Environment: Windows XP, Drools MR3
            Reporter: Brian Enderle
         Assigned To: Mark Proctor


The equality operators (== & !=) are not working correctly when comparing a value to a global.  This holds true for globals of the type java.lang.Character and java.lang.String.

Given:

Person object with sex set to 'M'

rule "Must be male"
   when
      $p : Person ( sex == 'M' )
   then
      System.out.println ( "- This is a man" );
end

rule "Cannot be a man"
   when
      $p : Person ( sex != 'M')
   then
      System.out.println ( "- This must be a woman")
end

Results:
- This is a man



If we replace the 'M' with the global "maleCode" and set it to 'M' in our calling program then,


gloabl java.lang.Character maleCode;

rule "Must be male"
   when
      $p : Person ( sex == maleCode )
   then
      System.out.println ( "- This is a man" );
end

rule "Cannot be a man"
   when
      $p : Person ( sex != maleCode)
   then
      System.out.println ( "- This must be a woman")
end

Results:
- This is a man
- This must be a woman

Both rules are passing when one, the latter, should fail
