>
> In the unit tests which uses the embedded servlet container an intermittent 
> issue can occur without this change, because those tests start the container 
> in a specific port, which is available at the start of the unit tests. 
> However, in some corner cases, it can happen that the port is being available 
> at the start of the test, but some process occupies that port meanwhile, 
> leading to a `java.net.BindException: Address already in use` exception 
> during the unit test's execution.
> The goal of this ticket is resolve this by introducing a retry mechanism when 
> starting the embedded servlet container.
