When having constraints like this,

"    $p: Person() \n" +
"    String(this == \"someString\" + $p)\n"

the build ends with
Failed to coerce : InvalidExpressionErrorResult: Arithmetic operation requires compatible types. Found class java.lang.String and class org.drools.model.codegen.execmodel.domain.Person
and
Unable to Analyse Expression this == "someString" + $p

This works without using executable model.
