https://issues.jboss.org/browse/JBRULES-2788?page=com.atlassian.jira.plug...
]
Mark Proctor resolved JBRULES-2788.
-----------------------------------
Fix Version/s: 5.2.0.CR1
(was: 5.2.0.M1)
Resolution: Done
I added a null check for this:
if ( factHandle == null ) {
throw new IllegalArgumentException( "FactHandle cannot be null " );
}
NPE in AbstractWorkingMemory due to session.retract(null)
---------------------------------------------------------
Key: JBRULES-2788
URL: https://issues.jboss.org/browse/JBRULES-2788
Project: Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: drools-core (expert)
Affects Versions: 5.1.1.FINAL
Reporter: Wolfgang Laun
Assignee: Mark Proctor
Fix For: 5.2.0.CR1
StatefulKnowledgeSession kSession = ...;
kSession.retract( null );
Notice that this might occur if kSession.getFactHandle() returns null because the fact
object
is invalid or already gone etc.
The above call causes
java.lang.NullPointerException
at org.drools.common.AbstractWorkingMemory.retract(AbstractWorkingMemory.java:1261)
at org.drools.common.AbstractWorkingMemory.retract(AbstractWorkingMemory.java:1242)
at
org.drools.impl.StatefulKnowledgeSessionImpl.retract(StatefulKnowledgeSessionImpl.java:255)
at resource.Main.exec(Main.java:92)
Expected: This should be ignored, or throw an Exception with a reasonable diagnostic.
(Javadoc does not say that an exception may be thrown.)
