TestContainers Could not find a valid Docker environment

Question

Running the same version of TestContainers 1.15.3 in one project is working correctly detecting docker etc but in another it is unable to start due to some sort of signing issue?

This looks to be caused by an issue in Adopt Open JDK as documented here:

https://github.com/adoptium/temurin-build/issues/1211#issuecomment-521392147 github.com/testcontainers/testcontainers-java/issues/1773

Switching over to Oracle JDK 12 has resolved the issue.
