[ https://issues.jboss.org/browse/DROOLS-923?page=com.atlassian.jira.plugin... ] Mario Fusco resolved DROOLS-923. -------------------------------- Release Notes Text: The NullPointerException reported by Tibor is not caused by a concurrency issue, but by the LRU cache that we introduced to workaround this other problem https://bugzilla.redhat.com/show_bug.cgi?id=1273368 That cache by default has a max size of 100 items https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/main... and increasing this size makes the NPE to disappear. Resolution: Done -- This message was sent by Atlassian JIRA (v6.4.11#64026)
