When using Java 8 scripting in the deployed application, I can see Error message in the log: 15:08:57,960 ERROR [stderr] (http-/127.0.0.1:8080-1) ScriptEngineManager providers.next(): javax.script.ScriptEngineFactory: Provider com.sun.script.javascript.RhinoScriptEngineFactory not found Sample Java code to reproduce the issue: new ScriptEngineManager().getEngineByName("nashorn").eval("print('Hello')");
To be clear about the behavior. The scripting itself works, but the ERROR message is present in the log file.
Upstream issue https://issues.jboss.org/browse/WFLY-3991 has been filed. This will not be fixed in EAP 6.
