Description (last modified by taylor.smock)

What steps will reproduce the problem?

Have some data in a layer (attached osm file)

I was downloading this query with a bounding box of 23.8858377;-129.375;52.4827802;-62.2265625

[out:json][timeout:25];
// gather results
(
  // query for all cases where the various synonyms for gnis id's match
  nwr["tiger:PLACENS"];
);
// print results
out body;
>;

What is the expected result?

Data downloads and is rendered

What happens instead?

Apparently this exception!

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

javax.json.JsonException: I/O error while parsing JSON
[...snip...]
Caused by: java.net.SocketTimeoutException: Read timed out

It looks like this was either due to a network issue, or the server didn't respond in time. Probably the latter, but if you have flaky internet, it could have been the former.

Anyway, it looks like we started to read the JSON, then something came along and interrupted the stream from the server, which caused a JsonException, which, since it is a runtime exception, caused us to show the bug report window.

In order to fix this, we'd probably want to do something like

src/org/openstreetmap/josm/io/OsmJsonReader.java

+                IllegalDataException ide = new IllegalDataException(exception.getCause());
+                ide.addSuppressed(exception);
+                throw ide;
+            } else {
+                throw exception;
+            }
+        }
+    }
     /**

I'd prefer to throw the SocketException, since that will give a better description of what happened, but I don't have a good place to put the catch, as I am limited by the IllegalDataException constraint. I could change the signature of the method so that it can throw an IOException, but I don't know how many plugins that would affect.

If we do go with something like what I wrote, we might just wrap the entire JsonException in an IllegalDataException. Not great, since our current utils for explaining exceptions will probably just tell the user that there was a json exception, not that there was a socket exception. So the catch block would just look like throw new IllegalDataException(exception).

I leave it to your infinite wisdom. It was completely reproducible last night (3 times) and I can't get it to repro this morning. Thanks for taking a look!

Replying to watmildon:

It was completely reproducible last night (3 times) and I can't get it to repro this morning.

That isn't surprising. Either it was a connection issue for you, or other people didn't file a bug report. In any case, I was able to reproduce it in tests by have a stream that returned a character, and then errored out.

TBH, I was kind of surprised to see that JsonException was a runtime exception. I would have expected it to be a checked exception.

Thanks for taking a look!

No problem. Thanks for reporting the ticket. I didn't see any duplicates for this either, which is surprising. I would have expected it or something like it to have been reported at least once.

I was doing a lot of work against the public overpass last night.. maybe it was cutting me off and this is how it gets bubbled up? hmmm.

Resolution:	→ fixed
Status:	new → closed

In 18656/josm:

Fix #22680: Unexpected exception when downloading GeoJSON

This occurs when we start to read the JSON, then something comes along and
interrupts the stream from the server. This then causes a JsonException
(a RuntimeException) to be thrown.

This patch catches the JsonException and then either rethrows it if the
cause was not an IOException or throws a new IllegalDataException with
the IOException as the cause and the JsonException as a suppressed exception.

comment:8 by taylor.smock, 22 months ago

In 18658/josm:

See #22680: Unexpected exception when downloading GeoJSON

This primarily adds a non-regression test, but also narrows the IOException
to SocketException to better match the exception type and adds a specific
catch for parsing issues.
