Bug #14753

Updated by François ARMAND over 3 years ago

UPDATE: as of JDK15, nashorn is removed.  

 Since OpenJDK 11, we get a warning: "Warning: Nashorn engine is planned to be removed from a future JDK release".  

 The fact that nashorn will be removed is terrible, and we will need to address that. Some reference links seems to tell that we will need to switch to GraalVM at some point:  

 junit-team/junit5#1481

 https://medium.com/graalvm/oracle-graalvm-announces-support-for-nashorn-migration-c04810d75c1f 


 In the meantime, we get a bad, red error message at startup, and we should really hide it, because rudder user really don't care about that. We need to add at startup options: 

 <pre> 
 -Dnashorn.args="--no-deprecation-warning" 
 </pre>
