Repository Manager OSS 3.19.0 failing to start

Since upgrading to OSS 3.19.0 I am unable to start the nexus service, which returns error:
Error occurred during initialization of VM
java/lang/ClassNotFoundException: error in opening JAR file

I updated my java environment which was previously:
openjdk version “1.8.0_191”
OpenJDK Runtime Environment (build 1.8.0_191-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

It is worth noting I am running this on an EC2 instance using Amazon Linux.

Are there any solutions to this?

Seems like something is wrong with the install? Not sure why there is a “._org…” file in lib/endorsed folder.
