Summary: Wrong pattern cloning causes missing FromNode sharing and eventually
a NPE
Key: DROOLS-2241
URL: https://issues.jboss.org/browse/DROOLS-2241
Project: Drools
Issue Type: Bug
Reporter: Mario Fusco
Assignee: Mario Fusco
Wrong cloning of a pattern having a FromNode as source causes wrong initialization of both
node and pattern which in turn prevents sharing of FromNode when possible.
Even worse when the duplicated FromNode are part of a subnetwork also the RiaNode at the
end of the subnetwork is wrongly initialized leading to a NPE like the following:
{node}
java.lang.NullPointerException
at org.drools.core.reteoo.RiaPathMemory.initDataDriven(RiaPathMemory.java:35)
at org.drools.core.reteoo.PathMemory.<init>(PathMemory.java:50)
{node}
