      Description

      FULL PRODUCT VERSION :
      C:\>java -version
      java version "1.8.0_91"
      Java(TM) SE Runtime Environment (build 1.8.0_91-b15)
      Java HotSpot(TM) 64-Bit Server VM (build 25.91-b15, mixed mode)

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 10.0.15063]

      EXTRA RELEVANT SYSTEM CONFIGURATION :
      I was trying to build a Class that would create an instance of JerseyClient.

      A DESCRIPTION OF THE PROBLEM :
      the code I was compiling is:

      package com.predictions3.client;
       
      import org.glassfish.jersey.client.JerseyClient;
      import org.glassfish.jersey.client.JerseyClientBuilder;
      import org.glassfish.jersey.client.JerseyWebTarget;
      import javax.ws.rs.core.MediaType;
      import javax.ws.rs.core.Link;
      import javax.ws.rs.core.Response;

      import predictions3.Prediction;



      public class PredictionsJersey2Client {

       private static final String REST_URI = "http://localhost:8080/predictions3/resourcesP/";

          private JerseyClient client = new JerseyClient();
         
          public static void main(String args) {
      PredictionsJersey2Client donut = new PredictionsJersey2Client();
      Prediction pred = donut.getXmlPrediction(2);
      System.out.print(pred);
      }

          public Prediction getXmlPrediction(int id) {
      return client.target(REST_URI).path(String.valueOf(id)).request(MediaType.APPLICATION_XML).get(Prediction.class);
          }
      }


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. import relevant classes as shown above

      2. define a custom Java Class ( standalone) that attempts to run a Jersey2 Client instance.

      Note: This compiler bug only happens when I try to compile a custom .java file. The compiler works fine in all other attempts to compile other source code.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      I expected a Java Class file to be created.

      ERROR MESSAGES/STACK TRACES THAT OCCUR :

      C:\DEV\RESTful WS Projects\Predictions_Client\com\predictions3>javac PredictionsJersey2Client.java
      An exception has occurred in the compiler (1.8.0_91). Please file a bug against the Java compiler via the Java bug reporting page (http://bugreport.java.com) after checking the Bug Database (http://bugs.java.com) for duplicates.
