[mkgmap-dev] PrecompSeaGenerator - which geotools version?

Sat Oct 27 11:20:07 BST 2018

Hi all,

I tried to find a geotools version which is compatible with Java11, but it seems this is not yet available.
I was however able to compile and execute the PrecompSeaGenerator with version 19.3.
The program prints a warning about an illegal attempt to close a file but seems to work after that.
I think that means we have to wait until the geotools devs do have a version that supports Java11
before we can update mkgmap to use that. The good thing is  that I did not have to change the sources,
so the change should be easy enough.

Gerd

Betreff: [mkgmap-dev] PrecompSeaGenerator - which geotools version?

Hi,

I tried to update my build environment for OSM maps, but with
current mkgmap versions, I have some problems to get the SeaGenerator
working together with geotools.

Neither the old one I used until now with an older mkgmap version,
nor newer ones seem to work. With 19.3 I get the following error:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.geotools.resources.NIOUtilities (file:/usr/share/java/mkgmap-SeaGenerator/gt-metadata.jar) to method java.nio.DirectByteBuffer.cleaner()

        at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:499)

Any idea, what goes wrong?
What would be the correct splitter version and geotools version for
mkgmap-r4245?

 Thanks,
  Thorsten
