Tested with "refresh at opening" and "auto-refresh" enabled. Steps to reproduce: 1. Import the sample project from bug 541555 (https://bugs.eclipse.org/bugs/attachment.cgi?id=277552). 2. Open the error log. 3. Open the "new 54555" diagram. It should display a single node with the Oboe logo and be dirty ("refresh at opening"). 4. If it did not open automatically, open the aird editor on the representations.aird. 5. "File > Close All" to close both opened editors. Two successive popups will ask if you want to save the changes. Answer "No" to both. The editors close properly, but an error appears in the error log: eclipse.buildId=unknown java.version=1.8.0_181 java.vendor=Oracle Corporation BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk,
