jurisdiction policy files are not signed by the expected signer!

[Campbell, Lance]

Mac OS
openjdk version "1.8.0_222"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_222-b10)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.222-b10, mixed mode)

I am currently getting this error message on my Mac when I try to make a connection using StartTLS to SparkPost for sending an email:

Caused by: java.lang.SecurityException: The jurisdiction policy files are not signed by the expected signer! (Policy files are specific per major JDK release.Ensure the correct version is installed.)

Could you please advise.

Thanks,
