// an actual eclipse exists; PatchVal causes code to run that will end up running `ResourcesPlugin.getWorkspace()`, which
// goes down a rabbit hole of pinging off of various static fields (or `getX()` calls which return static fields), all
// of which are `null` until the plugin they belong to is properly initialized.
// This code is work in progress to 'hack' the initialization of each plugin one-by-one, but I doubt this is the right
// way to do it, as I bet it's fragile (will break when eclipse updates rather easily), and who knows how many fields
// and things need to be initialized.
// A better plan would be to start an actual, real eclipse, by telling `EclipseStarter.startup` to launch some sort of
// application (or at least a bunch of bundles/products/apps, including the JDT). This will then take long enough that
// it'll need to be cached and re-used for each test or the Eclipse test run would take far too long.
