Is it OK to use the json-plugin-2.5.13 with the new struts-2.5.14, since my application does not have any crafted JSON messages? > JSONResult exception in struts2-json-plugin-2.5.14.1.jar > --------------------------------------------------------- > > Key: WW-4911 > URL: https://issues.apache.org/jira/browse/WW-4911 > Project: Struts 2 > Issue Type: Bug > Components: Plugin - JSON > Affects Versions: 2.5.14.1 > Environment: Java, JSON, Hibernate, Struts2 > Reporter: nick > Priority: Critical > Labels: easyfix > Fix For: 2.5.15 > > Original Estimate: 24h > Remaining Estimate: 24h > > Error log: > 12:09:16,381 ERROR [stderr] (http-/127.0.0.1:8080-4) ERROR DefaultActionInvocation There was an exception while instantiating the result of type org.apache.struts2.json.JSONResult > 12:09:16,397 ERROR [stderr] (http-/127.0.0.1:8080-4)  com.opensymphony.xwork2.inject.DependencyException: com.opensymphony.xwork2.inject.ContainerImpl$MissingDependencyException: No mapping found for dependency [type=org.apache.struts2.json.JSONUtil, name='default'] in public void org.apache.struts2.json.JSONResult.setJsonUtil(org.apache.struts2.json.JSONUtil). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
