[rules-users] Regression 5.1->5.2 with conflicting ClassNames

[Swindells, Thomas]

I'm in the progress of updating from Drools 5.1 to 5.2 in the hope of solving problems we are having with intermittent mysteriously missing activations.

I've found a regression with the compiler which I don't know whether anybody else has noticed before.

In our application we've got two Content classes in different packages, and unfortunately one of our rule files has to reason over both of them.
In drools 5.1 this was fine, we imported one of them and then used the fully qualified name for the other.

I'm just upgrading to 5.2.0-Final and this no longer works. When resolving the unqualified class name drools/mvel(?) was choosing the package that we hadn't imported!
This obviously then gave us loads of misleading error messages about not being able to find fields.

Fully quallifiying all references to both classes fixed the issue but something obviously isn't behaving properly.

Thomas
