TransitDataService Method Error

[Andrew Hall]

Greetings,

We're implementing Virginia Railway Express with OneBusAway transit-data-federation-webapp and api-webapp.  We're receiving this error when we make an API call "java.lang.IllegalArgumentException: fromIndex(595) > toIndex(540)"

Sometimes we receive the error and sometimes we receive the normal arrivals and departures.  The other agencies on that OBA instance work well so I think it's isolated to VRE.

I looked in the catalina.out logs and saw the below three messages.  

Please help us resolve this issue.  Thank you for your help.

Sincerely,

Andrew Hall

Greetings,

We're implementing Virginia Railway Express with OneBusAway and we're receiving an error message when we make a call to the OBA server.  The call returns the error message "java.lang.IllegalArgumentException: fromIndex(442) > toIndex(397)"  Other agencies on the same OBA instance work properly so I think it's isolated to VRE's GTFS.  Please assist us with solving this issue.  Thank you for your help.

I investigated the logs and I found these messages in the catalina.out log.

Is this with or without VRE's GTFS being corrected for the 'backwards' shapes?

(VRE's GTFS reuses the same shape for trips in both directions along a route; there is a transformer in the OBA GTFS transformer to fix this so that trips are associated with shapes that progress in the same direction as the trip.)

I would not be surprised by that error if it's with an unpatched VRE GTFS file - but if the GTFS been fixed so that shape points and trips progress in the same direction, then this is indeed a distinct (although related) issue.

The exception is actually getting thrown from the call to Arrays.binarySearch() here:

Andrew,
Not sure if you're still looking into this, but it may be related to bad real-time data, specifically stop_sequence values that don't match with stop_ids, or out-of-range stop_sequences for a given trip_id.

See https://github.com/OneBusAway/onebusaway-application-modules/issues/136.

Sean,

Thanks to you and Kurt for your responses. 

I removed the real-time configuration and I'm still having similar issues with VRE.

This is the temporary patch, to get past the issue:

https://github.com/camsys/onebusaway-application-modules/commit/01e6337dba823e109c7c1b5d367fdb727bca35e9

(you can cherry-pick that commit, or make the change yourself).

I hope to add some unit tests around the issue and get a better
understanding of it. But the error is implying invalid shapes or it
could perhaps simply be a bug in the indexes corresponding to the
shapes.

Once I can confirm the issue, I'll try to push this out to master.

Thank you for the link to the patch.  We got VRE to work by building the application without the shapes.txt file.
