Description

In tiered classloading environments, lifecycle start --> BeansDeployer deploy --> AnnotatedElementFactory.newAnnotatedType(Class<X>) sometimes throws ClassNotFoundException and NoClassDefFoundError's from the following methods
Field[] fields = SecurityUtil.doPrivilegedGetDeclaredFields(annotatedClass);
Method[] methods = SecurityUtil.doPrivilegedGetDeclaredMethods(annotatedClass);
These exceptions and errors are typically due to incorrect or erroneous application packaging of classes and dependencies.

I would like OpenWebBeans to continue loading other classes even if one/few classes cannot be loaded correctly i.e. the assumption is that we don't punish the majority for the crimes of a few. We define Managed Beans ONLY for classes that yield a AnnotatedType.

At runtime, if the application exercises any CDI function on the "bad" classes, then the results are indeterminate.
I will attach a patch that will explain my approach of fixing this.
