Description
For query like this, assuming xxx is not Person's field,
query Q1
$p : Person($xxx : xxx)
end
standard-drl gives an error like this:
text=Field Reader does not exist for declaration '$xxx' in '$xxx : xxx' in the rule 'Q1']]
but exec-model raises NPE. It should give a better error message:
