While removing custom results via

ro.sync.exml.workspace.api.results ResultsManager#removeResult(String, DocumentPositionedInfo),

https://www.oxygenxml.com/InstData/Edit ... ionedInfo-

Oxygen (Version: 20.1, build 2020010914) sometimes throws an exception with the application freezing afterwards:

Does anybody have an idea, what could be the cause of this error? I am not calling the method on the event dispatcher thread. Could this be the issue?

Thanks,

Hi Gregor,

Our components are not thread safe so try to call all additions or removal of content from the results list on the AWT thread using something like SwingUtilities.invokeLater(Runnable). I cannot guarantee this is the problem, so if it happens again please give us more details, maybe some small code samples about how you add and remove those documentpositioninfo elements.

Regards,
Radu
