[rules-users] Error due to same class name

[Michael Anstis]

The guided rule editors really, really, I mean really, do not handle
multiple classes with the same simple name in different packages at all
well.

Even if you only use a single class in a single rule (I.e. do not attempt
to use x.y.z.MyClass and a.b.c.MyClass) the overall DRL being compiled can
lead to issues as you're effectively creating:

"import x.y.z.MyClass

rule a
when
MyClass (...)
...
end"

and

"import a.b.c.MyClass

rule b
when
MyClass (...)
...
end"

I suspect issues to arise with class FQCN resolution in at least one of
those rules.

If you cannot use different simple names then my advice is to use free-form
DRL for these classes; using the FQCN in the rule and exclude the imports
(from the "Config" tab).
