Re: Kawa 1.6.98/1.6.99 compiler bug?

Per,

Thanks for the info and pointer to the preferred methods for Java interface.

Can I suggest to whomever maintains the Kawa documentation that this info be 
added to the pages that defines the "mostly deprecated" syntax (rooted at: 
http://www.gnu.org/software/kawa/Low-level-functions.html) to steer us novices 
in the right direction?

Thanks again!

Tom
