      Description

        In PNGImageReader.readNullTerminatedString() if we pass String whose length is same as maxLen but without null at the end. We will just read that non-null terminated string without throwing any Exception.

        We should throw a proper exception that header contains non-null terminated String.

        This bug is created after analyzing JDK-8191023.
