Configuration Files on the Classpath present in a Jar File will not load

[smflorentino]

I'm currently writing a plugin to enable AppInsights on my project (it's a Maven project). I created a plugin, also a Maven project, and bundled the ApplicationInsights.xml file inside, as a resource. This works fine in my IDE, since the file is not inside of a jar, but on the filesystem. However, once I package the project and use the resulting artifact as a dependency (a jar of the plugin gets placed on the classpath), AppInsights sees the configuration file but cannot load it from the jar.

I tracked down the source of the bug - if the ApplicationInsights.xml file is present in a jar on the classpath, the SDK still tries to load as a file - but it should be loaded as a resource or input stream, since its not a file on the filesystem per se.

I'm able to reproduce this as a failing unit test in the SDK, as I've pushed to my branch on the PR, where I'm hoping a fix can be discussed/implemented.

Other people seem to be experiencing the problem too - as I found this StackOverflow question when searching for answers:
