Updating from 1.2.3 to 1.5.0 breaks

[SElab2019]

When I try to upgrade Jsonassert from 1.2.3 to version after 1.4.0. The following code breaks.

public static void jsonSchema2Xsd(InputStream isJsonSchema, OutputStream osXSD) throws JSONException, ParserConfigurationException, TransformerException {
		Reader inputReader = new InputStreamReader(isJsonSchema);
		JSONObject rawSchema = new JSONObject(new JSONTokener(inputReader));
}

The code should pass. But it throws an error:

incompatible types: java.io.Reader cannot be converted to java.lang.String
