At https://gitlab.eclipse.org/eclipse/escet/escet/-/merge_requests/73#note_10795, @ahofkamp notes: > An error in execution like `cd bin; ./cif2cif` throws an error due to missing arguments (which is correct). It also pops up a graphical window from the VM saying it failed with the execution options and flags details. You have to close that window manually before the prompt returns. As such the `bin` programs are useless for automagic use in their current form.
