[PATCH] x2, import of incomplete NMEA sentences causes exception

Reported by: FauxFaux Owned by: framm
Priority: major Milestone:
Component: Core Version: latest
Keywords: StringIndexOutOfBoundsException; NMEA log import Cc:


Many simplistic NMEA loggers just stop writing whenever is convenient, not bothering to put a complete sentence into the log file.

For example, a recent log of mine ended with:


...which is obviously incomplete, and invalid.

This produces the "An unexpected exception has occoured." dialog, with something like the following trace:

java.lang.StringIndexOutOfBoundsException: String index out of range: 3
	at java.lang.String.substring(
	at org.openstreetmap.josm.actions.OpenAction.openFileAsNmea(

Perhaps ignoring errors that occour in the last sentence of a file would be sensible?

Could you adapt your patch slightly?

a) Ignore all errors in the NMEA file

b) When there have been errors, print an message dialog at the end of the import telling the number of errors.

#1630 has another error, but same topic

#1648 has a patch and a more systematic (good!) approach on listing and resolving all/a lot of possible errors regarding NMEA log import
