ASF subversion and git services commented on OPENJPA-2672: ---------------------------------------------------------- Commit 1764159 from [~fyrewyld] in branch 'openjpa/branches/2.2.x' [ https://svn.apache.org/r1764159 ] OPENJPA-2672: ConfigurationImpl.loadGlobals() has java.util.ConcurrentModificationException vulnerability > ConfigurationImpl.loadGlobals() has java.util.ConcurrentModificationException > vulnerability > ------------------------------------------------------------------------------------------- > > Key: OPENJPA-2672 > URL: https://issues.apache.org/jira/browse/OPENJPA-2672 > Project: OpenJPA > Issue Type: Bug > Components: lib > Affects Versions: 2.2.3 > Reporter: Jody Grassel > Assignee: Jody Grassel > Attachments: OPENJPA_22X-2672.patch > > > The following block in the loadGlobals() method: > // let system properties override other globals > try { > fromProperties(new HashMap( > AccessController.doPrivileged( > J2DoPrivHelper.getPropertiesAction()))); > retrieves a Properties object from System.getProperties(), which is passed to > HashMap's ctor. The ctor interacts with an enumerator associated with the > Properties object to populate the new HashMap instance. However, if another > thread mutates the JVM's System Properties, it can result in a > ConcurrentModificationException as observed below: > Caused by: java.util.ConcurrentModificationException > at java.util.Hashtable$Enumerator.next(Hashtable.java:1256) > at java.util.HashMap.putAllForCreate(HashMap.java:566) > at java.util.HashMap.<init>(HashMap.java:310) > at > org.apache.openjpa.lib.conf.ConfigurationImpl.loadGlobals(ConfigurationImpl.java:189) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
