[rules-users] Drools 5.2.0.M2 is not compatible with JDK 1.5?
Hi all,
I'm just trying out the default Drools project created with Eclipse plugin
but already getting errors:
java.lang.NoSuchMethodError:
java.util.LinkedList.peekLast()Ljava/lang/Object;

peekLast() is a JDK 1.6 method.. so does that means from Drools 5.2x
onwards, I have to upgrade my JDK? Which sadly I can't cause my company is
using OSX Leopard, stuck with JDK 1.5 :(
