[rules-users] unable to determine value type class *** URGENT***

[Knapp, Barry]

Oh I missed a third option from Ken.

1) upgrade to Drools 5
2) Rollback FP
3) We had the same issue with IBM JDK. Upgrade to java 6R4 to solve the problem

Has anyone found a solution to the "Websphere FP23" issue yet?

>From reading this thread it sounds like we have 2 options:
Upgrade to 5.0 or rollback the Websphere FP.

What have others decided to do?

Thanks for any input.
Barry
