New JUnit tests sometimes fail on Jenkins

[lwrage]

Please describe the problem your proposed feature would address
New tests developed on Windows or Mac sometimes work fine during development but fail on Jenkins.

What is the impact of the problem?
Extra effort to remember the cause (case insensitive file system during development, case sensitive file system on build server) and fix it.

Describe the solution you'd like
Tests should fail during development if model files are loaded using a path where capitalization doesn't exactly match the file system path even on Windows and MacOS.
