When updating a KieContainer with updateToVersion with a change in a declared type two consecutive times, a NullPointerException is raised.
Minimal example DRL triggering the issue (notice at least two declared types are needed):
declare FactType1
x : int
end
declare FactType2
y : int
end
first update:
declare FactType1
x : int
z : int
end
declare FactType2
y : int
end
second update:
declare FactType1
x : int
z : int
w : int
end
declare FactType2
y : int
end
The second update will raise the following exception:
java.lang.NullPointerException at org.drools.compiler.kie.util.ChangeSetBuilder.build(ChangeSetBuilder.java:106) at org.drools.compiler.kie.builder.impl.InternalKieModule.getChanges(InternalKieModule.java:132) at org.drools.compiler.kie.builder.impl.KieContainerImpl.update(KieContainerImpl.java:241) at org.drools.compiler.kie.builder.impl.KieContainerImpl.update(KieContainerImpl.java:237) at org.drools.compiler.kie.builder.impl.KieContainerImpl.updateToVersion(KieContainerImpl.java:195) at org.example.reproducer.KjarUpdateTest.update(KjarUpdateTest.java:37) at org.example.reproducer.KjarUpdateTest.testConsecutiveUpdates(KjarUpdateTest.java:48)
