      The executable model will break when parsing a rule like below where there is a method call with an argument and binding and comparison happening at the same time. The old model will have this work. If the method call has no arguments then this works as well.

      rule "Rule that breaks ExecutableModel"
@filename("rules.drl")
ruleflow-group "RFG-1"
salience 5
    when
        $values: List()
        $cwv:    ClassWithValue( $value: value.charAt(5) == '5' )
    then
        $values.add($value);
end

      The executable model will have this work when the binding and comparison are multiple constraints like so:

      package com.example.rulesimport java.util.*import com.example.*rule "Rule that breaks ExecutableModel"
@filename("rules.drl")
ruleflow-group "RFG-1"
salience 5
    when
        $values: List()
        $cwv:    ClassWithValue( $value: value.charAt(5), $value == '5' )
    then
        $values.add($value);
end
