Client request invoked via a ClientProxy built by ProxyFactory corrupts string parameters

Specifically, I updated TestClient.java and MyTestResource.java to have a new method: @GET @Produces("text/plain") @Path("/query-param") public ClientResponse<String> getQueryParam(@QueryParam("queryParam") String queryParam); I then added the following tests to EncodingTest.java (which mimic the encodingCharacter() method contained therein): @Test public void testPathParamWithDoublePercent() { String paramWithDoublePercent = "start%%end"; System.out.println("*** " + paramWithDoublePercent); ClientResponse<String> returned = testClient.getPathParam(paramWithDoublePercent); Assert.assertNotNull(returned); Assert.assertEquals(HttpURLConnection.HTTP_OK, returned.getStatus()); Assert.assertEquals(paramWithDoublePercent, returned.getEntity()); } @Test public void testPathParamWithBraces() { String paramWithBraces = "start{param}end"; System.out.println("*** " + paramWithBraces); ClientResponse<String> returned = testClient.getPathParam(paramWithBraces); Assert.assertNotNull(returned); Assert.assertEquals(HttpURLConnection.HTTP_OK, returned.getStatus()); Assert.assertEquals(paramWithBraces, returned.getEntity()); } @Test public void testPathParamWithLifePercentDeath() { String paramWithLifePercentDeath = "life%death"; System.out.println("*** " + paramWithLifePercentDeath); ClientResponse<String> returned = testClient.getPathParam(paramWithLifePercentDeath); Assert.assertNotNull(returned); Assert.assertEquals(HttpURLConnection.HTTP_OK, returned.getStatus()); Assert.assertEquals(paramWithLifePercentDeath, returned.getEntity()); } @Test public void testQueryParamWithDoublePercent() { String paramWithDoublePercent = "start%%end"; System.out.println("*** " + paramWithDoublePercent); ClientResponse<String> returned = testClient.getQueryParam(paramWithDoublePercent); Assert.assertNotNull(returned); Assert.assertEquals(HttpURLConnection.HTTP_OK, returned.getStatus()); Assert.assertEquals(paramWithDoublePercent, returned.getEntity()); } @Test public void testQueryParamWithBraces() { String paramWithBraces = "start{param}end"; System.out.println("*** " + paramWithBraces); ClientResponse<String> returned = testClient.getQueryParam(paramWithBraces); Assert.assertNotNull(returned); Assert.assertEquals(HttpURLConnection.HTTP_OK, returned.getStatus()); Assert.assertEquals(paramWithBraces, returned.getEntity()); } @Test public void testQueryParamWithLifePercentDeath() { String paramWithLifePercentDeath = "life%death"; System.out.println("*** " + paramWithLifePercentDeath); ClientResponse<String> returned = testClient.getQueryParam(paramWithLifePercentDeath); Assert.assertNotNull(returned); Assert.assertEquals(HttpURLConnection.HTTP_OK, returned.getStatus()); Assert.assertEquals(paramWithLifePercentDeath, returned.getEntity()); } The summary of the test run follows: Results : Failed tests: testPathParamWithLifePercentDeath(org.jboss.resteasy.test.encoding.EncodingTest) testQueryParamWithLifePercentDeath(org.jboss.resteasy.test.encoding.EncodingTest) Tests in error: testPathParamWithDoublePercent(org.jboss.resteasy.test.encoding.EncodingTest) testPathParamWithBraces(org.jboss.resteasy.test.encoding.EncodingTest) testQueryParamWithDoublePercent(org.jboss.resteasy.test.encoding.EncodingTest) testQueryParamWithBraces(org.jboss.resteasy.test.encoding.EncodingTest) Note that four of the test results in exceptions occuring within RestEASY code. The two failed tests fail because the value returned does not equal the value passed as a parameter.
