[protege-user] freezing on Ubuntu, fine on macOS

[Benjamin Aaron Degenhart]

Hi there,

I have the latest Protege 5.5.0-Beta-5 installed on Ubuntu 18.04 and on
macOS Mojave and open the exact same Ontology on both (it has 2 direct
imports and 5 indirect imports).

There are some Classes and their respective Individuals that when simply
clicked on in Ubuntu, freezes Protege forever. Also no error in the command
line. Clicking on the same class/individual on macOS works flawless.

Any idea how I might resolve this freezing-issue?

Best regards,
Benjamin
