    [ https://issues.jboss.org/browse/DROOLS-1562?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13405827#comment-13405827 ] 

Maciej Swiderski commented on DROOLS-1562:
------------------------------------------

[~mfusco] there seems to be two issues:

- one in KieModuleMetaData as illustrated in the attached stack trace
- another in updateToVersion method of KieContainerImpl that leads to following NPE:

{code}
java.lang.NullPointerException: null
	at org.drools.compiler.kie.util.ChangeSetBuilder.build(ChangeSetBuilder.java:57) ~[drools-compiler-7.1.0-20170508.233901-66.jar:7.1.0-SNAPSHOT]
	at org.drools.compiler.kie.builder.impl.KieContainerImpl.update(KieContainerImpl.java:236) ~[drools-compiler-7.1.0-20170508.233901-66.jar:7.1.0-SNAPSHOT]
