PI83901: THE CONTEXT CLASSLOADER IS NOT GETTING SET PROPERLY WHEN LOADING CDI EXTENSIONS AT APP STARTUP

Fixes are available

APAR status

Closed as program error.

Error description

The context classloader is not getting set properly when
loading CDI extensions at app startup.

The same BackedAnnotatedType is trying to load
DefaultConfigSourceProvider from both app1 and app2, but
app1
and app2 should each have their own BackedAnnotatedType
instances.

The Thread Context ClassLoader was not being set when CDI
extensions were loaded, which is leading to errors with third
party libaries that expected a TCCL when loading their CDI
extensions. An example of such an error is as follows:
