Rule compilation can fail when using an attribute/method of OOPath provided variable

Having a test like this:
https://gist.github.com/mackaypeter/d8b576ce34d42794da559308b1854aff

Produces the following error:

Unable to Analyse Expression this.getName() == "joe":
[Error: unable to resolve method using strict-mode: org.drools.compiler.oopath.MyTest$Parent.getName()]
[Near : {... this.getName() == "joe" ....}]
                  ^
[Line: 4, Column: 2] : [Rule name='R']

It seems like it tries to look for the method definition in the Parent class instead of the Child class. The rule works correctly when there's a getName method defined in Parent. Meaning the rule compiles and fires correctly.
