Carsten Ziegeler closed SLING-6831. ----------------------------------- > ConcurrentModificationException in OSGi Installer > ------------------------------------------------- > > Key: SLING-6831 > URL: https://issues.apache.org/jira/browse/SLING-6831 > Project: Sling > Issue Type: Bug > Components: Installer > Affects Versions: Installer Core 3.8.6 > Reporter: David Bosschaert > Assignee: Carsten Ziegeler > Fix For: Installer Core 3.8.8 > > Attachments: SLING-6831.patch > > > Under certain scenarios I'm getting: > {code}java.util.ConcurrentModificationException: null > at java.util.HashMap$HashIterator.nextNode(HashMap.java:1437) > at java.util.HashMap$KeyIterator.next(HashMap.java:1461) > at > org.apache.sling.installer.core.impl.OsgiInstallerImpl.getInstallationState(OsgiInstallerImpl.java:1390) > ...{code} > To me this seems caused by the fact that the Map datastructure in the > PersistentResourceList is non-concurrent. > PersistentResourceList.getEntityIds() returns the map's values directly. This > is what is used in OsgiInstallerImpl line 1390: > {code} > public Collection<String> getEntityIds() { > return this.data.keySet(); > }{code} > And the client code iterates over that, causing the exception. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
