pyimagej interefering with Tkinter GUI on Mac

I have an application using pyimagej for image processing and want to make a very simple interface for the users to provide some inputs. I am using tkinter for this gui. When I initialize pyimagej either in that script or one of its imports, it fails to produce the gui, but does not crash. It just shows the following message:
`2019-05-31 16:47:01.581 python[27137:9099880] In -[NSApplication(NSQuietSafeQuit) _updateCanQuitQuietlyAndSafely], _LSSetApplicationInformationItem(NSCanQuitQuietlyAndSafely) returned error -50`

Here is some dummy example code that reproduces this:
```
import imagej
import tkinter as tk
ij = imagej.init('sc.fiji:fiji:2.0.0-pre-10')
root = tk.Tk()
tk.Label(root, text='Test1').grid(row=0, column=0)
tk.Checkbutton(root, text='Test2').grid(row=1, column=0)
root.mainloop()
```

Without the imagej initialization, it runs fine. It happens both with a maven initialization and when wrapping the local Fiji installation. This problem **does not** reproduce on Windows for me (there, the gui comes up as expected) and I don't know whether it reproduces on Linux.
I do get this issue on my Mac running macOS 10.14.5.

Start by reproducing the minimal example around imagej.init('sc.fiji:fiji:2.0.0-pre-10') followed by tkinter.Tk() on macOS 10.14.5, then compare it with the local Fiji initialization path and the Windows result. Done means the Tkinter window appears and remains usable after either pyimagej initialization path, without the reported macOS message preventing the GUI.
