      Description

      A DESCRIPTION OF THE PROBLEM :
      When calling jdk.internal.net.http.ResponseSubscribers$HttpResponseInputStream.read(byte[], int, int) with len = 0 an assertion fails because it requires len to be positive

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Make sure to apply the -ea option to enable assertions
      2. Create a HttpClient
      3. send a request using BodyHandlers.ofInputStream() as the responseBodyHandler
      4. Get the body from the response and call read(byte[], int, int) with len = 0

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The read method should just return without doing anything as stated by the JavaDoc on InputStream.read(byte[], int, int): "If len is zero, then no bytes are read and 0 is returned"
      ACTUAL -
      Exception in thread "main" java.lang.AssertionError
      at java.net.http/jdk.internal.net.http.ResponseSubscribers$HttpResponseInputStream.read(ResponseSubscribers.java:449)
      at Main.main(Main.java:11)
