Can somebody give me an idea of what is going on because I keep getting rather strange results from my tests. So, I have a maven project in IntelliJ and if i run this code (note the cyrillic string) inside the IDE the output is as expected.

JsonObject json = new JsonObject();

json.addProperty("message", "тест");

System.out.println("TEST:"+json.get("message").getAsString());

Output in IDE: TEST:тест

But if I package the project in a jar file the encoding of the JsonObject messes up somehow and the code above results in:

Output in console from jar: TEST:????

Things I tried:

• forcing the JVM to use -Dfile.enconding=UTF-8 just to see if this affects it but nothing changed.




• getting the bytes of the json.get("message").getAsString() and creating a new string with specified encoding new String( bytes, StandardCharsets.UTF_8)




• checked the IntelliJ run arguments of the project (nothing is specified)




• the problem persists with all characters with ASCII value above 127 (mentioning ASCII because UTF and most of the encodings inherit the first 127 character values from ASCII)




• It is not a console related problem because the same issue persists on UI elements that support UTF-8 here is an example: http://prntscr.com/lmca64 . This still persists ONLY on the app of the exported jar!

Do you have any idea what might cause this inconsistent behavior?

Update*:
After further testing here is the output of the following code:

    JsonObject json = new JsonObject();

    json.addProperty("message", "тест");

    byte jsonBytes = json.get("message").getAsString().getBytes();

    for(byte b : jsonBytes) {

        System.out.print(b+" ");

    }

    System.out.println();

    byte stringBytes = "тест".getBytes();

    for(byte b : stringBytes) {

        System.out.print(b+" ");

    }

IDE output:

-47 -126 -48 -75 -47 -127 -47 -126

-47 -126 -48 -75 -47 -127 -47 -126

Compiled jar console output:

63 63 63 63

63 63 63 63

This in terms shows that both of the strings are the same but once packaged into a jar something happens.

Here is my pom.xml. May be I am doing something wrong while exporting the jar in wrong encoding?
