[jboss-jira] [JBoss JIRA] Created: (JBRULES-3074) Null pointer at org.drools.time.impl.JDKTimerService.removeJob(JDKTimerService.java:103)

Null pointer at org.drools.time.impl.JDKTimerService.removeJob(JDKTimerService.java:103) ----------------------------------------------------------------------------------------- Key: JBRULES-3074 URL: https://issues.jboss.org/browse/JBRULES-3074 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.1.1.FINAL Environment: Ubuntu Reporter: Richard Ambridge Assignee: Mark Proctor Priority: Blocker Attachments: DroolsRuleTest.java, Item.java, rule1.drl Using drools with time based rules and saliance, the saliance is not used when firing the rules This only happens when multiple objects update at the same time. e.g. Rule 1 is salience 1000 dialect "mvel" when $i : Item(val==10) Item(val==11, this after [0s, 1m] $i) Rule 2 is salience 1000 dialect "mvel" when $i : Item(val==10) not( Item(val==11, this after [0s,1m] $i)) Rule3 is salience 100 when $i : Item(val==11) Then we insert 3 items with val==10 Rule2 is activated 3 times... Then we insert an item with val==11 Note, with a val==10 and val==11 in the memory, Rule 1 will activate, and Rule 3 will activate However, Rule1 should fire first.. as its saliance is high For the first item it does, but then the Rule 3 fires before 2nd item does. Audit log is attached, but summary is Object inserted (1), Item: val==10 Activation created: Rule 2 (1) Object inserted (2), Item: val==10 Activation created: Rule 2 (2) Object inserted (3), Item: val==10 Activation created: Rule 2 (3) Object inserted (4), Item: val==11 Activation created: Rule 1 (1) Activation created: Rule 1 (2) Activation created: Rule 1 (3) Activation created: Rule 3 (4) Activation cancelled: Rule 2 (1) Activation cancelled: Rule 2 (2) Activation cancelled: Rule 2 (3) .. here we have 4 activations, 3 for Rule1 (saliance 1000), 1 for Rule3(saliance 100) Activation executed Rule 1 (1) Activation executed Rule 3 (4) //WRONG Activation cancelled: Rule 1 (2) Activation cancelled: Rule 1 (3) Activation created: Rule 2 (2) Activation created: Rule 2 (3) Note, this works fine in Drools 5.0 In Drools 5.2.0 CR1 a null pointer is thrown (another issue will be logged for that) -- This message is automatically generated by JIRA.
