Unable to read application / json message in Response response

Question

I am testing a REST API, and when I make a GET call to retrieve the resources, it leads to a 500 Internal Server Error and prints a return message with media type to it application/json:

[
  {
    "messageType": "Some error type",
    "messageText": "Some message text",
    "moreInfo": "Some info"
  }
]

Note that in the output above, Json is inside []

I want to read the value messageTextfrom the output above received. I tried -

JsonObject jsonObject = response.readEntity(JsonObject.class);

but this leads to the following error:

java.lang.IllegalStateException: Entity input stream has already been closed.

Could you help me, how can I read the output message? I am using the Jersy library.
