RE: iPojo inner class instrumentation
Hi Clément,
Sorry to answer so late, but we just test your proposal.
We tried to disable "proxy" on C2 as suggested below, but no positive effect.
After that we tried to test our use-case with last 1.8.0 iPojo version.
We still had an exception, but with more information. Here it is:
java.lang.IllegalStateException: Cannot create the Nullable object, an unexpected error occurs: Invalid BundleContext.

Maybe the "Invalid BundleContext" is the cause of our problem?
We will test the use-case you mentioned below in our environment to check if it's working.

Hi,
I've tried to reproduce your scenario in:
http://svn.apache.org/viewvc?view=revision&revision=1045175
However, it works for me. I just remove C4 and directly call C3. Could you
highlight the differences ?
Regards,
Clement

RE: iPojo inner class instrumentation
Posted by Bigard Olivier <ob...@axway.com>.
We just checked: the Bundle is correctly and fully started when have the error...
One more information: we also have the following WARNING trace in standard output:
[WARNING] : [UseCaseConsumer.fdff9a89-3437-4b28-90ff-64f7a51ce77e] The dependency is not optional, however no service object can be injected in provider -> c4z.usecase.provider.UseCaseProviderApi

Hi,
Invalid Bundle Context means that the bundle is stopping or already
stopped, and so is not able to access the service registry anymore. Is it
your case?

Clement

RE: iPojo inner class instrumentation
Posted by Bigard Olivier <ob...@axway.com>.
Hi Clément,
We tried to execute your sample in our environment: it produced the same error described below.
We just modified a little your sources to make them run: we add a C4 Bundle that contains an iPojo instance that calls C3 "getFilter()" method in its "validate" callback.
We created one OSGi Bundle per component.
You can find these 4 OSGi Bundles in attachments.
Can you try to do following:
- start the 4 Bundles (C4 "validate" callback is correctly called) -> "My filter ... called" is produced in standard output
- stop C1 and C2 Bundles
- restart C1 and C2 Bundles
- "validate" callback is not correctly called -> only "My filter ..." is produced in standard output and the stacktrace below is produced
Thanks
Olivier

Hi,
Invalid Bundle Context means that the bundle is stopping or already
stopped, and so is not able to access the service registry anymore. Is it
your case?
