Thanks for the test. I continue to struggle with the last install. But still keep losing that battle though.

@0709wiwiwi in the video you seem to stay on the parent folder of belgium.

On desktop, open a folder means to enter the folder and press open:

Old version_old graph

[devemux86]

• Video 2: you correctly enter the graph folder and press open
• Video 1: you do not enter the graph folder
  You remain in parent folder and press open

[0709wiwiwi]

New version_new graph
No matter how I click I can't get it right.

In this video you seem to enter the graph folder and then press open.
This should work, unless the graph folder does not contain valid data.

Are you sure you are running the Cruiser 3.0.20?
Are you sure the graph folder contains valid data?

If the folder does not contain routing data,
there is immediately a warning message after press open.

Select the "Settings | App theme | Default", restart Cruiser and try again.

Maybe the file browser of Java's default theme works better on your Windows.

No change.

Ok let's stop for now. Time to get wiser.

I had the same problem. You have to upgrade your Java Environment. The Cruiser 3.0.20 (or graphhopper to be more precise) is using access methods not available in older Java Runtime Environments.
Exception in thread "Thread-9" java.lang.NoSuchMethodError: java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer;
at com.graphhopper.storage.MMapDataAccess.getBytes(MMapDataAccess.java:427).

@slwmr thanks, very nice!

@0709wiwiwi @slwmr what Java do you use?

I can add a compiler parameter to fix this in next update.
At least Java 11 should work properly?

[slwmr]

I had this error with Java 8. When I changed the start script to point to OpenJDK12 the offline routing with GH started to work without any problems.
Thank you for a great application. I'm also using it to show the results of some simple programming of my son. So maybe you contribute to the next generation of developers in this way ;) .

@0709wiwiwi @slwmr

Can you try on Java 8 the desktop Cruiser 3.0.21 (Beta) available here?

[0709wiwiwi]

Result is OK !

[slwmr]

I have tested the beta version with Java 8 as well. The offline routing is working!

[devemux86]

@0709wiwiwi @slwmr thanks for the report and for finding the Java error!

The fix will be included in the next desktop Cruiser update.

[devemux86]

It should work properly with desktop Cruiser 3.0.21.
