Jenkins / JENKINS-57727 ConcurrentModificationException from lock step Issue Type: Bug Assignee: Tobias Gruetzmacher Components: lockable-resources-plugin Created: 2019-05-28 22:05 Environment: Jenkins 2.150.2 Lockable Resources Plugin 2.5 Priority: Minor Reporter: William Brode I got this ConcurrentModificationException when using "lock" step for several pipelines running on the same master at the same time. I believe it can happen when new locks are being created while the list of locks is being looped through. java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:909) at java.util.ArrayList$Itr.next(ArrayList.java:859) at org.jenkins.plugins.lockableresources.LockableResourcesManager.fromName(LockableResourcesManager.java:156) at org.jenkins.plugins.lockableresources.queue.LockableResourcesStruct.<init>(LockableResourcesStruct.java:83) at org.jenkins.plugins.lockableresources.LockStepExecution.start(LockStepExecution.java:62) at org.jenkinsci.plugins.workflow.cps.DSL.invokeStep(DSL.java:268) at org.jenkinsci.plugins.workflow.cps.DSL.invokeMethod(DSL.java:176) at org.jenkinsci.plugins.workflow.cps.CpsScript.invokeMethod(CpsScript.java:122) at org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:48) at org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:48) at org.codehaus.groovy.runtime.callsite.AbstractCallSite.call(AbstractCallSite.java:113) at com.cloudbees.groovy.cps.sandbox.DefaultInvoker.methodCall(DefaultInvoker.java:20) Add Comment

Re: ConcurrentModificationException from lock step Getting the same issue for Jenkins 2.190.2 and Lockable Resources Plugin2.7. Has happened a few times and seems to be happening when many jobs have started at the same time and they are all trying to use the lock step.
