nullSafeEqualityComparison in PackageBuilder is not null safe ------------------------------------------------------------- Key: JBRULES-3544 URL: https://issues.jboss.org/browse/JBRULES-3544 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-compiler Affects Versions: 5.4.0.Final Reporter: Davide Grohmann Assignee: Mario Fusco Fix For: 5.4.1.Final, 5.5.0.Beta1 The method nullSafeEqualityComparison uses the compareTo method which is not null safe. The issue can be reproduce by calling nullSafeEqualityComparison with the second parameter null. There are two possible fixes: 1) use equals instead of compareTo in nullSafeEqualityComparison 2) or add a check for the non nullity of the second argument.
