HtmlUnitRequestBuilder corrupts the parent RequestBuilder [SPR-14584]

[spring-projects-issues]

Rob Winch opened SPR-14584 and commented

HtmlUnitRequestBuilder corrupts the parent RequestBuilder. For example:

String pathInfo = "/foo/bar";
MockMvc mockMvc = MockMvcBuilders.standaloneSetup(new HelloController())
		.defaultRequest(get("/"))
		.build();

// passes
assertThat(mockMvc.perform(get(pathInfo)).andReturn().getRequest().getPathInfo(), equalTo(pathInfo));

// corrupts the pathInfo of the parent builder
mockMvc.perform(requestBuilder);

// fails because the parent builder's path info is now set to "/"	
assertThat(mockMvc.perform(get(pathInfo)).andReturn().getRequest().getPathInfo(), equalTo(pathInfo));

Affects: 4.3.2, 5.0 M1
