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:
