What version of the product are you using? On what operating system?

Running under Windows XP SP3, started the JNAerator from JNLP, but same for 
java -jar call.

Hi Kai,

Thanks for this report :-)
The JNA runtime output is undertested, I'm afraid.
The issue comes from some bit fields-related code, and JNA does not support bit 
fields.
I've checked in a fix, but the output will skip the bit fields and hence 
produce some inconsistent structures.
