This repository contains a JUnit test class
JOptCommandLinePropertySourceTest
that demonstrates that the implementation of Spring's JOptCommandLinePropertySource selects
the option alias names enumerated by getPropertyNames() in an inconsistent way. The test class
also shows different property name enumeration strategies that, in the author's opinion, produce
more helpful results.
The Spring Boot application
WrongPropertyNameDemoApplication
demonstrates how command line arguments processed by JOpt can be injected into the environment of
a Spring Boot application (and thus be referenced in @Configuration classes).
