logfile endpoint returns HTTP 406 on Accept: text/plain

[joshiste]

The logfile endpoint responds with a content of type text/plain.
When doing the get request with Accept: text/plain a HTTP 406 (Not Acceptable) is returned. I'd expected such a request to succeed.

It looks like that only Accept: */* (or omitting the header) works.

Thanks for the report, @joshiste. Looks like this affects all three web stacks. Here's an addition to LogFileWebEndpointWebIntegrationTests that fails on Jersey, Spring MVC, and Reactive:

@Test
public void getRequestThatAcceptsTextPlainProducesResponseWithLogFile() {
	TestPropertyValues.of("logging.file:" + this.logFile.getAbsolutePath())
			.applyTo(context);
	client.get().uri("/actuator/logfile").accept(MediaType.TEXT_PLAIN).exchange()
			.expectStatus().isOk().expectBody(String.class).isEqualTo("--TEST--");
}
