java.lang.AbstractMethodError: com.sun.jna.Structure.getFieldOrder()Ljava/util/List;

[Volker Berlin]

The download file at https://github.com/downloads/dblock/waffle/Waffle.1.5.zip does not contain a platform.jar.

I download it from https://github.com/twall/jna/blob/3.5.0/dist/platform.jar?raw=true

Now I receive the follow exception:

I must have a problem with my eyes. Now I have see the platform.jar and it work. But the jar files in the waffle download are not identical to the jna downloads.

[Daniel Doubrovkine]

The Waffle ones came from the Maven repo and they are slightly different in their meta descriptions. That's annoying since there're 2 versions of the JARs for 3.5.0 in the wild and both are good ones. JNA has fixed that or plans to fix it.
