Steps to reproduce

1. Follow the Get Started instruction in README:

git clone https://github.com/vmware/concord
cd concord
docker/build_images.sh
docker-compose -f docker/compose/simple4.yml up

2. Docker container of concord_ethrpc returned the above error and exited.

Context

• Used versions (Concord version): commit 85862f8b6a079d3e5db989d7934aee2cd42ba46b
• Docker version: 17.09.0-ce, build afdb6d4
• Docker-compose version: 1.27.4, build 40524192
• Host OS: Ubuntu 16.04.3/ 20.04.2

What worked for me i have mentioned in below steps:
step1: navigate to folder concord-> tools-> ethrpc in your local installation.
step2: change the version no. from 2.9.10 to 2.10.0 of the following dependency in pom.xml file as below.

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-core</artifactId>
        <!-- <version>2.9.10</version> -->
        <version>2.10.0</version>
    </dependency>

step3: run the below commands again

   docker/build_images.sh
   docker-compose -f docker/compose/simple4.yml up

Finally with this the build was successfull and i was able to run the 4-node concord in my system
