<div dir="ltr">Ciao,<div>I'm using 6.1.0.Final - btw, thank you for this release!</div><div><br></div><div>I have an issue as sometimes I'm getting an NPE from the RightTupleList, as documented in the snippet of stacktrace below. Unfortunately, I'm not able to provide as I did in the past a reproducer, because this error occurs only occasionally after the application has been running for quite some time - this error does not happen with the rule unit tests suite.</div>
<div><br></div><div>Therefore I would like to ask you the following questions, please.</div><div><br></div><div>1. would the stacktrace below be enough for you to possibly identify the kind of error which is happening in this case?<br>
</div><div>2. shall I go ahead and raise a JIRA just with this information? I've checked on JIRA but couldn't find any "similar" issue for this case </div><div><br></div><div>Finally, if the answers are both "no", does it mean that the only way I could provide an helpful feedback, is to log all the session incoming facts indefinitely, so to later "craft" an log-replay reproducer; or would you suggest another way I can do this more efficiently?</div>
<div><br></div><div>Thank you very much in advance for your feedback</div><div>Ciao</div><div><br></div><div><br></div><div><div>Caused by: java.lang.NullPointerException</div><div> at org.drools.core.util.index.RightTupleList.matches(RightTupleList.java:264) [drools-core-6.1.0.Final.jar:6.1.0.Final]</div>
