OpenAPI3_1SerializationTest.java:1377:

assertEquals(Json31.pretty(openAPI), "{\n" +
        "  \"openapi\" : \"3.1.0\",\n" +
        "  \"components\" : {\n" +
        "    \"schemas\" : {\n" +
        "      \"test\" : true\n" +
        "    }\n" +
        "  }\n" +
        "}");

Json31.pretty(String) uses Jackson's DefaultIndenter which uses the machine's line separator (System.getProperty("line.separator")), i.e. "\r\n" under Windows OS.
