Re: "Uncaught translation error" when transforming Kawa-compiled classes with dex

[Kay Zheng <l04m33@gmail.com>]

Hi Sonny,

Thanks for the suggestion.

I carelessly left out an important fact, that I've compiled the same
app against the 2.4 branch this way and it worked well, so I'd suspect
it's some changes in Kawa that caused this error. Not necessarily a
bug, though.

Regards,
Kay Z.
