Hello, I may have found a bug derived from 2.18
Before 2.18, i can specified an header like: <setHeader headerName="myHeader"> <javaScript>[{"firstField": "firstValue", "secondField":"secondValue"}]</javaScript> </setHeader> In my bean, *myHeader* will be cast to *ArrayList<HashMap<String,Object>>* After 2.18 upgrade i had an error *'java.lang.ClassCastException: jdk.nashorn.api.scripting.ScriptObjectMirror cannot be cast to java.util.List'* Can you help me? Is it a camel bug or an jdk8 issue? -- View this message in context: http://camel.465427.n5.nabble.com/Getting-ready-for-Apache-Camel-2-18-Release-tp5786942p5788108.html Sent from the Camel Development mailing list archive at Nabble.com.
