[mkgmap-dev] Commit r4270: improve reader for polish (*.mp) format

Sat Feb 9 23:41:02 GMT 2019

Hi Gerd,

I have tried to compile some more complicated mp. First problem is, that 
restriction placed on the beginning of the file give multiple warnings, 
like:

SEVERE (RoadNetwork): 00008001.mp: 1 can't locate arc from 'via' node  1 
to 'to' node 171 on way 431744
SEVERE (RoadNetwork): 00008001.mp: 4 can't locate arc from 'via' node  4 
to 'to' node 59519 on way 1020461
SEVERE (RoadNetwork): 00008001.mp: 8 can't locate arc from 'via' node  8 
to 'to' node 80234 on way 812265

Then mkgmap crashes:

java.lang.NullPointerException

Exiting - if you want to carry on regardless, use the --keep-going option

If I move restriction to the end of file, then there is no warning, but 
crash is the same:

java.lang.NullPointerException
