Spring Boot Application startup issues | Endpoints are not loaded

I have Spring Boot application with the following package structure
src/
├── de.mypackages.alivetestservice/
│ ├── adapters/
│ ├── config/
│ ├── domain/
│ ├── exceptions/
│ ├── representations/
│ └── ServiceApplication.java
The adapters/ package represent all elements regarding communication (http & messaging).
The config/ package defines configurations for rabbitmq, feign clients, spring security, Sentry, swagger
The domain/ package contains the application's business logic
The exceptions/ & representations packages contains exceptions and Dto definitions.
Startup on a local machine works without any issues. But when the application is build in docker image and is started by our Spinnaker orchestration unit within a Azure Kubernetes cluster the application does not register properly.
It randomly starts up correctly with this output:
https://jsfiddle.net/f63utbqz/
And then again... it sometimes starts incorrectly with this output:
https://jsfiddle.net/h9vzLdfg/
It seems that there are key components missing on the startup of the application. Because I can not find any log for RequestMappingHandlerMapping or RequestMappingHandlerAdapter.
My application is started with the following ServiceApplication.java file:
package de.mypackages.alivetestservice;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication(scanBasePackages = "de.mypackages.alivetestservice")
public class ServiceApplication {
public static void main(String[] args) {
SpringApplication.run(AliveTestServiceApplication.class, args);
}
}
My Dockerfile configuration looks like this:
FROM openjdk:8-jdk-alpine
ARG JAR_FILE
ADD ${JAR_FILE} app.jar
ENTRYPOINT ["java", "-jar", "/app.jar"]

Can anybody please help on , understanding this thread dump

sonarqube "Apply project exclusions" very slow

We are using sonarqube 5.1.1 and often the step "Apply project exclusions" is very, very slow. In the range of 1-2.5 hours sometimes.
We have "Global Source File Exclusions" to exclude 2 patterns:
**/swagger-ui/**
**/*.min.js
I'm not sure how recent a change this is because our sonarqube builds are run nightly.
Update: I did a thread dump as requested and it looks like it's waiting on an db connection.

Spring boot process is not shutdown with an embeded Tomcat

I'm using Spring-Boot- 1.1.4 and running on Ubuntu 14 with Java 1.7.
I built a web appliaction based on MongoDB and an embedded Tomcat.
The issue is that I cann't gracefully shutdown my application since there are some blocked Tomcat threads.
Here is my thread dump:

Although there are several discussions on this issue, I couldn't find what I'm doing wrong, I mean, I didn't do anything related to the shutdown process.
Important, the issue is not reproduced on windows.
Can someone please instruct me on this?

It looks like you've found a bug in Spring Boot. Thanks for bringing it to our attention. I've opened an issue to address it.
We haven't seen this problem before so there must be something about your application or environment that we haven't encountered. Can you please comment on the Spring Boot issue with some more details on how to reproduce the problem?

The complete answer can be found here
To make things short, I configured my Spring Boot application manually (#EnableAutoConfiguration is disabled ), so, I added the dispatcher servlet by creating it using a contructor:
#Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
public DispatcherServlet dispatcherServlet(WebApplicationContext ctx) {
DispatcherServlet dispatcherServlet = new DispatcherServlet(ctx);
return dispatcherServlet;
}
This caused the shutdown thread to be blocked.
