Exception when starting vaadin 14 website with springboot

I developed a vaadin website including spring boot. The website is already running in production mode and the tomcat starts, but the following exception comes up the first time you access it via the browser:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

I created a maven build run configuration in Eclipse that has "package -Pproduction" as the goal.
When it runs it creates a jar file in the target directory that works.

Handling RequestRejectedException - ExceptionLoggingFilter

I was getting this error when a user was missing a parameter in the request and it was coming like www.foo.com/fooId//info and it was throwing a RequestRejectedException and returning a 500 error to the user.
Error Log:

To catch this exception, I added this filter:
#Component
#Slf4j
#Order(Ordered.HIGHEST_PRECEDENCE)
public class RequestRejectedExceptionHandler extends OncePerRequestFilter {
#Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
throws ServletException, IOException {
try {
filterChain.doFilter(request, response);
} catch (RequestRejectedException e) {
log.error("400 - Bad Request");
response.setStatus(400);
response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
}
}
}
In postman now, it is returning a 400 bad request as I want it to, however in my logs, I can see this ERROR still being logged as uncaught, and not too sure why and need some advice:

You are likely using an unsupported version of Spring Cloud Sleuth if you are seeing these logs.
The logs from o.s.c.s.i.web.ExceptionLoggingFilter are coming from the Spring Cloud Sleuth dependency.
The ExceptionLoggingFilter is intended to help with log correlation. From the reference documenation
Sleuth configures the logging context with variables including the service name (%{spring.zipkin.service.name}) and the trace ID (%{traceId}). These help you connect logs with distributed traces and allow you choice in what tools you use to troubleshoot your services.
Once you find any log with an error, you can look for the trace ID in the message.
In this case, the ExceptionLoggingFilter is likely executed before your custom filter.
Note that the ExceptionLoggingFilter is disabled by default since Spring Cloud Sleuth 2.2.3 and removed completely in 3.x.
If you upgrade to a supported version of Sleuth, you will not see these logs.

With 3.1.x we are adding support for Tomcat Valve instrumentation so that ExceptionLoggingFilter is no longer needed. We will instrument all logs that come from within tomcat.

ApplicationConfigurationMetadataResolver : Failed to retrieve properties for resource:Docker Resource

Hi I'm running Spring Cloud Data Flow Server (v2.6.2-SNAPSHOT) in openshift environment. I get the NullPointerException every time I schedule or launch a task from SCDF saying Failed to retrieve properties for resource. I'm registering My Springboot batch application as Docker image in SCDF. Below is the Exception trace.
Though it's not affecting the task execution in anyway, It generates of lots of logs in SCDF container. And we usually run our batches every 10 minutes.
I searched about this issue and found links to github where it says it's fixed in older version. But not sure how it's happening in V2.6.2. I hope this is the issue the ticket was about.
Github ticket: ApplicationConfigurationMetadataResolver
Let me know if there's anything I can do fix this issue.

This looks like an authorization issue based on what I see from the code.
Check if you have the correct auth config as mentioned here

Spring-boot app has spurious internal server errors while serving static assets

We have a spring boot 2.0.2 application that serves a few things and also some static content from a webjar using the webjar locator core dependency.
This works most of the time, but in approx. 0.5-0.8% of the calls to the same URL I just get an error 500.
I tried pinpointing the problem, but there is no error message at all, just the 500 status in the apache log.
When setting the logger of the ResourceHttpRequestHandler to TRACE, I see that it was able to determine the content type of the file and the next I see the access log line.
Has anyone an idea what might be wrong or how I can get more logs that let me find the reason for that?
Here are the only logs I see for these broken calls:
Accesslog looks like this:
10.XXX.XX.XX - - [11/Jun/2018:16:02:50 +0200] "GET /YYY/styles.0cce9718deac950ad0c6.bundle.css HTTP/1.1" 500 198411 "" ""
"-:-" correlation_id=Wx6BCgq6AT8AACzd0l8AAAAj duration=159ms
Regular log for that call:
2018-06-11T16:02:50.778+0200;YYY;2732;1.4;https-jsse-nio2-10.XXX.XX.XX-8443-exec-8:32;2018061;Wx6BCgq6AT8AACzd0l8AAAAj;20c40980-6d80-11e8-8dca-02000ab22d32;TRACE;ResourceHttpRequestHandler;Determined
media type 'text/css' for class path resource
[META-INF/resources/webjars/frontend/0.0.0/styles.0cce9718deac950ad0c6.bundle.css]
The project is a pretty plain spring boot project using embedded tomcat.
[EDIT]
I also set the org.apache.tomcat to DEBUG and this doesn't shed some light either. I do see a few exceptions now, but these only complain about close socket and this shouldn't be the problem, because the response has already been sent.
java.lang.Exception: null
at org.apache.tomcat.util.net.Nio2Endpoint.closeSocket(Nio2Endpoint.java:344)
...

It looks like the reason is HTTP Statuscode 500 in Tomcat AccesLog on ClientAbortException / BrokenPipe
I set the whole application to trace and finally could see the exception:
2018-06-12T09:12:47.409+0200;KTO;21116;1.4;https-jsse-nio2-10.XXX.XX.XX-8443-exec-10:34;2018061;Wx9ybgq6AT8AADruMgAAAAAw;0236d480-6e10-11e8-8085-02000ab22d32;DEBUG;DispatcherServlet;Could not complete request

Cause:
This exception can mean that the connection to the client browser is aborted before the response is fully transfer. It is a harmless warning as it can be due to transient network problems or the browser aborts/refreshes the page before it loaded.
A list of other causes are:
The user closed the browser before the page loaded.
Their internet connection failed during loading.
They went to another page before the page loaded.
The browser timed the connection out before the page loaded (would have to be a large page).
Solution:
This can be ignored, unless there are other issues that are currently occurring. For example, if the JIRA application server is throwing a lot of these, it might be a sign of a performance problem. See ClientAbortException because of closing a page before it finished loading for further information.
