Overview

The dcaebe-tools seems to have the hard to track bug inside the docker container.
The tools.Main class only catch the RuntimeExpetion but the current version of the DcaeRestClient throws the LinkageError (that isn't catch):

Technical detalis 

It seems that some of the packages are missing (in the pom.xml file):
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${org.springframework.version}</version>
</dependency>

And
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.26</version>
</dependency>

to solve another issue with the SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". warring.

With those dependencies, the container starts correctly but the request to the dcae_be (from dcae_tools) return the Internal Error 500, and still the dcae-tools can't do his work.

When the user (in local deployment) create the "BasicMonitoringTemplate" resource using sdc ui, and the container will restart this error not will be throw and container end the work with these logs:
