Jevon Wright commented on JBRULES-2218:
---------------------------------------

I got this error as well in Drools 5.0.1 in Eclipse 3.5, Windows XP. It is because reserved words are being used as part of the rule definition (position?). My rule was:

rule "Name"
  when
    ...
    run : RunInstanceWire( eContainer == sw, from == operation, name == "run" )
    ...
    
  then
    ...

end

Removing the "from" keyword resolved the error. This is a critical bug for me, however the previous engine (4.0.7) was working fine in Eclipse 3.5, so I will be reverting back until this is resolved.
