[Christopher Schnick]

Given a small reproducer code snippet that is not part of a test and not 
in the jfx repo, what is the quickest way to run this with a debugger 
attached with multiple different jfx builds/development branches to see 
the difference? I feel like my workflow is not optimal and would like to 
hear how others do it
