[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1487) access to store property in MapBackedClassLoader should be synchronized

access to store property in MapBackedClassLoader should be synchronized ----------------------------------------------------------------------- Key: JBRULES-1487 URL: http://jira.jboss.com/jira/browse/JBRULES-1487 Project: JBoss Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: Reteoo Affects Versions: 4.0.4 Reporter: Jan Boboli Assigned To: Mark Proctor Fix For: 4.0.5, 5.0.0-M1 In MapBackedClassLoader three methods have access to the "store" property - addClass, fastFindClass and getResourceAsStream. fastFindClass is used in synchronized loadClass method, but addClass modifies the store without any synchronization. MapBackedClassLoader is connected to one rulebase which can be shared between different working memory, so it is possible that multiple threads access the store concurently.
