martinweiler opened a new issue, #1753: URL: https://github.com/apache/incubator-kie-issues/issues/1753
Using a process definition with a higher number of BusinessRulesTask handler nodes, we see a performance issue under load: *"kogito-event-executor-xx"* runs `org.kie.internal.utils.ChainedProperties.read(ChainedProperties.java:229)` and it relies on `java.util.jar.JarFile.getEntry()` that creates a lock monitor. ``` "kogito-event-executor-12" #68 daemon prio=5 os_prio=0 cpu=4286.47ms elapsed=215.32s tid=0x00007f2f3d989670 nid=0x6a waiting for monitor entry [0x00007f2f3c7b6000] java.lang.Thread.State: BLOCKED (on object monitor) at java.util.zip.ZipFile.getEntry([email protected]/ZipFile.java:337) - locked <0x00000007408c6270> (a sun.net.www.protocol.jar.URLJarFile) at java.util.jar.JarFile.getEntry([email protected]/JarFile.java:513) at sun.net.www.protocol.jar.URLJarFile.getEntry([email protected]/URLJarFile.java:131) at sun.net.www.protocol.jar.JarURLConnection.connect([email protected]/JarURLConnection.java:135) at sun.net.www.protocol.jar.JarURLConnection.getInputStream([email protected]/JarURLConnection.java:175) at java.net.URL.openStream([email protected]/URL.java:1161) at org.kie.internal.utils.ChainedProperties.read(ChainedProperties.java:229) at org.kie.internal.utils.ChainedProperties.getChainedProperties(ChainedProperties.java:74) at org.kie.internal.utils.ChainedProperties.getChainedProperties(ChainedProperties.java:70) at org.drools.core.impl.RuleBaseFactory.newKnowledgeSessionConfiguration(RuleBaseFactory.java:155) at org.drools.project.model.ProjectRuntime.getConfForSession(ProjectRuntime.java:83) at org.drools.project.model.ProjectRuntime.newKieSession(ProjectRuntime.java:67) at com.test.SampleProcess.lambda$process$136(DataProcess.java:2337) at com.test.SampleProcess$$Lambda$1018/0x0000000800706cc0.get(Unknown Source) at org.jbpm.workflow.instance.rule.AbstractRuleTypeEngine.getKieRuntime(AbstractRuleTypeEngine.java:35) at org.jbpm.bpmn2.rule.RuleFlowGroupRuleTypeEngineImpl.evaluate(RuleFlowGroupRuleTypeEngineImpl.java:39) ``` With multiple threads performing the same operation in parallel, we see many of them BLOCKED as in the above example. -- This is an automated message from the Apache Git Service.
