Jersey 1.19 Grizzly 2.3.25 and Umlaute in URL - JUnit tests does not work while browser access does

Question

In a RESTFul Jersey solution I am trying to receive URLs that contain German Umlaut characters e.g.

http://localhost:8085/hello/hello/echo/ÄÖÜßööü

When I enter such URLs with a browser I get correct results. When I test things with a JUnit test it doesn't work.

org.junit.ComparisonFailure: expected:<[ÄÖÜßäöü]> but was:<[ÃÃÃÃäöü]>
    at org.junit.Assert.assertEquals(Assert.java:115)
    at org.junit.Assert.assertEquals(Assert.java:144)
    at com.bitplan.rest.test.TestHello.testUmlaute(TestHello.java:43)

the debug output is:

http://localhost:8085/hello/hello/echo/%C3%84%C3%96%C3%9C%C3%9F%C3%A4%C3%B6%C3%BC
http://localhost:8085/hello/hello/echo/ÄÖÜßäöü
GET:hello/echo/ÃÃÃÃäöü

and so it seems the url is not handled correctly by Grizzly/Jersey.

How can I fix this or work around it?

I found: https://github.com/javaee/grizzly/issues/1377 and tried different encodings e.g. as proposed in https://stackoverflow.com/a/9542781/1497139 but that didn't make any difference.

I also set

server.getServerConfiguration().setDefaultQueryEncoding(Charsets.UTF8_CHARSET);

as outlined in https://github.com/javaee/grizzly/issues/1450 but still no luck

JUnit Test see https://github.com/BITPlan/com.bitplan.simplerest/blob/master/src/test/java/com/bitplan/rest/test/TestHello.java#L42

@Test
public void testUmlaute() throws Exception {
 super.startServer();
 URI uri=new URI("http://localhost:8085/hello/hello/echo/ÄÖÜßäöü");
 System.out.println(uri.toASCIIString());
 System.out.println(uri.toString());
 WebResource wrs = Client.create().resource(uri);
 String result= wrs.accept("text/html; charset=utf-8").get(String.class);
 assertEquals("ÄÖÜßäöü",result);
}

  }
}
