[weld-dev] Issue with weld 2.1.0.Final on OSGI

[Charles Moulliard]

Hi Jozef,

Thx for the info. Been able to figure out the issue by using 
Require-Bundle within my example otherwise the package was not imported.

Remark : I will have a look later on to PAx-CDI to allow to import 
packages of CDI and not like now using Require-Bundle

Regards,

Charles
