[rules-users] MVELDialectRuntimeData; local class incompatible

[TonyN]

I am trying to upgrade from 5.2Final to 5.4final and ran into this error.  It
seems that the rule engine (5.4) is having a hard time building the Knowlege
base using PKG directly from Guvnor 5.4.  It has no issues with DRL though.

Both the Drools Engine and the Guvnor are running Java 1.6.0_20.
Both are at 5.4Final.

Not sure where, what to check next, thanks a millions.
