Carlos Sierra Andrés commented on ARIES-1965:
---------------------------------------------
Hi [~maggu2810],
thx for reporting this. Can you tell us at which point in the application
lifecycle it is trying to load the class?
by the stack trace it looks like this is happening whie trying to serve the
request, but can you please confirm?
The different whiteboards involved should set the appropiate thread context
class loaders to the different involved bundles, but maybe we missed some. This
means your bundle should be set as the TCCL to serve the request, does your
bundle provide this classes or imports to other bundles that might have them?
Even though the whiteboard has those classes internally it does not mean it is
the one it is not finding them. If the whiteboard is setting the TCCL properly
to your bundle it should be your bundle the one that provided a implementation
of the factory, and the SPI declaration.
Carlos.
