ConcurrentModificationException

Component: unspecified Version: latest

Description (last modified by stoecker)

Running JOSM with livegps and surveyor plugin I get the error message from time to time.
After about 2.h hours testing several times within a short time.

Nevertheless the program is doing well.
Perhaps it is only a warning???

livegps is modifying the gpx track at the same time as EDT is trying to get length of the track to show tooltip text.

The exception can be fixed either by making GpxData thread safe (using ConcurrentLinkedQueue for GpxTrack.trackSegs instead of LinkedList will fix this concrete issue) or by acessing GpxData only in worker thread.
