Guillaume Nodet reassigned ARIES-867: ------------------------------------- Assignee: Guillaume Nodet > Deadlock if stopping a blueprint bundle while the blueprint container is in > the create state. > --------------------------------------------------------------------------------------------- > > Key: ARIES-867 > URL: https://issues.apache.org/jira/browse/ARIES-867 > Project: Aries > Issue Type: Bug > Components: Blueprint > Affects Versions: blueprint-0.3.1 > Environment: Felix 4.0.2, Fileinstall 3.2.4, Pax Logging 1.6.3. > Reporter: Marcel Hanser > Assignee: Guillaume Nodet > Attachments: com.test.deadlock.1.blueprint-0.0.1-SNAPSHOT.jar, > com.test.deadlock.2.stopper-0.0.1-SNAPSHOT.jar, felix-framework-4.0.2.zip, > stripped-threaddump.txt > > > Assume a updating mechanism which installs a bundle using fileinstall. It > places a bundle in a folder watched by fileinstall. If the bundle is removed > in a short manner a deadlock may occur. This issue can occur if a bundles > blueprintcontainer is registering services during the create state and the > bundle is stopped concurrently. See attached Threaddump. We also attached a > sample environment to reproduce the deadlock. > For reproduction: > - start the container in debug mode. > - put the com.test.deadlock.1.blueprint-0.0.1-SNAPSHOT.jar into the ./load > folder and wait for GRACE_PERIOD state of the blueprint container. > - set breakpoint on line 3205 in class org.apache.felix.framework.Felix. > - put the com.test.deadlock.2.stopper-0.0.1-SNAPSHOT.jar into the ./load > folder. > - skip the breakpoint the FIRST time! > - remove the com.test.deadlock.1.blueprint-0.0.1-SNAPSHOT.jar from ./load > folder, fileinstall will now remove the bundle, wait a until fileinstall > loggs the that. > - resuming now the debugger. This leads to the deadlock and to the attached > thread dump. > Richard S.Hall does describe the problem in the comment here: > https://issues.apache.org/jira/browse/FELIX-3393?focusedCommentId=13244548&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13244548 > You might consider to register services in a <code>open call</code>, if > easily possible. -- This message is automatically generated by JIRA.
