Subject Re: Problem during bundle manipulation in iPOJO
Date Wed, 25 Jan 2012 09:10:27 GMT
Hi,

This is a bug in the manipulator 1.8.2. We're working on it. It takes more time than expected
because Java 7 changes the byte code requirements, and those 'small' changes make the manipulation
a bit more tricky. So just use the 1.8.0 for now. 

Regards,

Clement

Depending if my code is in a try/catch or not, my build is successful or there is a fatal
error.
