With the latest versions (tried, back until 3316) of mkgmap i'm getting a NPE
with a new setup on an older 32Bit XP Machine:
java.lang.NullPointerException

Exiting - if you want to carry on regardless, use the --keep-going option
Number of ExitExceptions: 1
It is in this code segment:
public int compareTo(RoadDef other) {
// sort by city name - this is used to group together
// roads that have been split into segments
if(other == this)
return 0;
// TODO: look at what this is doing...
if(city != null && other.city != null)
return city.getName().compareTo(other.city.getName());
<--- Here happens
the NPE
if (hashCode() == other.hashCode())
return 0;
else if (hashCode() < other.hashCode())
return -1;
else
return 0;
}
*This happens when running with "--max-jobs=2" (it is a core2duo machine)
but when running with "--max-jobs=1" the error does NOT occur... :?*
Best regards, Uli
