CDI context propagation? Weld 3.1.0.Beta1 has something to say about that
by Matej Novotny
Hello,
Weld 3.1.0.Beta1 was released yesterday.
Along with bunch of other fixes[1] and/or features, this release contains first API for CDI context propagation.
Weld docs[2] contain more information on how to do that along with an example.
If you have a use case for this, please give it a spin.
The API is a first draft which was done with
MP Concurrency needs in mind and probably won't cover all the cases.
Which is precisely why we appreciate any feedback in this regard, we cannot cover use cases we don't know about :-)
Regards
Matej

PROBE-000014 - Caused by ClassNotFoundException: int
by Benjamin Confino
Hello
I found a PROBE-000014 error in my fat test suite which was Caused by:
java.lang.ClassNotFoundException: int cannot be found by
com.ibm.ws.org.jboss.weld.2.4.8_1.0.23.201811031441. Looking at the stack,
I think weld is the code deciding to do a class lookup on int, have you
ever seen this before? Any idea what might be triggering weld do lookup
int? I had a quick look at the application code and couldn't see anything
weird involving ints.
Here is the full stack:

BeanManagerImpl permits multiple Contexts per scope type: why?
by Laird Nelson
I noticed that BeanManagerImpl permits many Contexts to be indexed under a
given scope type
<https://github.com/weld/core/blob/d8a8cb64f3a9751dcac07c8d9eda0dd3a0e682b...>.
Why is that?
The CDI 2.0 specification says
<http://docs.jboss.org/cdi/spec/2.0/cdi-spec.html#contexts>:
"Associated with every scope type is a context object."
I took "a context object" to mean "exactly one context object" but maybe
I'm mistaken? Obviously Weld can do things outside of the specification
but I was curious what the use case might be here.
I do understand that certainly only one Context of a given scope type may
be active. I was just curious why the container even permits many to be
registered.
Best,
Laird
