Make BeansDeployer.deployFromClassPath(ScannerService) resilient to
ClassNotFoundException and NoClassDefFoundError's
---------------------------------------------------------------------------------------------------------------------
Key: OWB-468
URL: https://issues.apache.org/jira/browse/OWB-468
Project: OpenWebBeans
Issue Type: Bug
Components: Core, Java EE Integration, Lifecycle
Affects Versions: 1.0.0-alpha-2, 1.1.0, 1.0.1, 1.0.0
Environment: Windows Server 2003
Reporter: Rohit Dilip Kelapure
Assignee: Gurkan Erdogdu
Sometimes in tiered classloading environments during lifecycle start -->
BeansDeployer deploy --> AnnotatedElementFactory.newAnnotatedType(Class<X>)
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.
