Re: [rules-users] Drools 5.2.0.M2 is not compatible with JDK 1.5?
No, Drools 5.2 remains Java 1.5 compatible. The error you report has already
been identified and AFAIK fixed in master.

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 :(
