An implementation of one of the simple Global Libraries outlined in the Workflow Global Libraries Plugin README fails to run `steps.sh "echo ..."` and also ends the pipeline with a NotSerializableException, failing the build.

Pictures are attached of the source code for the library, the configuration of the global library within Jenkins, and the pipeline script being executed.

The console output of the build is:

The class must be declared implements Serializable. I will check if the doc needs to be updated.
