Spring Boot login page issue

Description

Unable to request default login form with logbook-spring-boot-starter in the dependencies. As soon I remove dependency or set logbook.filter.enable=false property - everything works as expected.

Expected Behavior

I should be able to access login form with enabled LogbookFilter

Actual Behavior

I have simple spring boot application with default authentication form. With logbook-spring-boot-starter - application starts, but I am unable to reach login form. For different web servers I can see next behaviour:

• Tomcat: continuous load
• Jetty: 500 error with “insufficient content written” message
• Undertow: empty reply from server with “Fixed length stream closed with with 1317 bytes remaining” message in logs

Context

• logbook-spring-boot-starter version: 1.13.0
• Spring Boot version: 2.1.2.RELEASE

My security configs:

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .authorizeRequests()
//          .antMatchers("/api/**").permitAll()
            .anyRequest().authenticated()
            .and().formLogin();
    }

If I uncomment line with permitAll - I still can not access login form, while api works as expected and I can see logged requests and responses.

I believe I finally found a fix. See #484
