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.
