14595	Silently failing if subject or reference sets contain a relation	bagage	Tyndare	"==== What steps will reproduce the problem?
1. Configure Conflation with sets that contain at least one relation
2. Click ""configure""

==== What is the expected result?

Either tables are filled, or an error pops ""Relations not supported yet""

==== What happens instead?

Tables are ""filled"" as if it was OK, but there are empty/contain nothing. No exception is shown in logs either. 

==== Please provide any additional information below. Attach a screenshot if possible.

By debugging a bit, I saw that the exception beeing thrown is:

java.lang.UnsupportedOperationException: Relations not supported yet.

To find it, I had to add in PleaseWaitRunnable.java:

{{{
    private void doRealRun() {
         //....
        try {
          } catch (final JosmRuntimeException | IllegalArgumentException | IllegalStateException |
                OsmTransferException | IOException | SAXException | InvocationTargetException | InterruptedException e) {
// added this code:
        } catch (Exception e) {
            e.printStackTrace();
        }
}}}
