OpenJDK 11 failure - running tests or application

[practicalli-johnny]

Using lein run or lein test when using OpenJDK 11 on Ubuntu Linux 20.04 fails. Leiningen version 2.9.1.

On the same machine with OpenJDK 8 the tests and application run.

Here is the start of the stack trace when using OpenJDK 11

$ lein test
Warning: implicit hook found: lein-cprop.plugin/hooks
Hooks are deprecated and will be removed in a future version.
Exception in thread "main" java.lang.ExceptionInInitializerError

I am not concerned about having the example project fixed for OpenJDK 11, however, would like to inform others that this project only seems to work for OpenJDK 8 so they will use an appropriate image.

Thank you.

Using the openjdk-8-lein-2.9.3 image in the configuration for this project will run successful builds.
