Docker: Java unable to resolve host IP address

Question

Problem

I am building an image containing the whole Oracle Commerce Guided Search platform, as it is possible to build the image in a successfully manner, the contained Java processes wont be able to run due to the following exception being raised:

Exception in thread "main" java.lang.RuntimeException: java.net.UnknownHostException:37863d1a232e: System error

By looking at the exception, is it clear that the hostname is being set to: 37863d1a232e.

Exception in thread "main" java.lang.RuntimeException: java.net.UnknownHostException: 37863d1a232e: System error

If I check OS $HOSTNAME, I get the following output:

[root@37de552fbd05 bin]# echo $HOSTNAME
37de552fbd05

Which is the same output shown at /etc/hosts/:

[root@37de552fbd05 bin]# cat /etc/hosts/
127.0.0.1       localhost
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
172.17.0.2      37de552fbd05

But, it is not the one shown at the exception.

What I have tried to workaround the issue?

1. I have used the --hostname flag as --hostname=localhost
2. I have tried to solution on this post: 32537977

Facts

1. I am using Mac OS (High Sierra, 10.13.5) as the hosting machine.
2. Docker community edition (Engine: 18.03.1-ce) is used to build the Docker Image.
3. The virtual OS is oraclelinux:7.2
4. Unfortunately, I have had no success performing the work-arounds mentioned above.

Unfortunately, I have had no success.

Questions

What could be the reason for this to be happening?
