I have a JakartaEE web project (JSF) with Java17 and Tomcat10.
Whenever I want to inject a class from Jakarta Servlet API (especially HttpServletRequest, but also ServletContext), I get a Weld Exception during proxy creation:
Caused by: java.lang.ClassNotFoundException: org.jboss.weld.proxy.WeldConstruct
I have created a minimal reproducer project, only containing a single bean and a single JSF file: https://github.com/metaxmx/WeldInjectionBugReproducer
After some debugging for the source of the problem, I found that it is most likely rooted in the Java11+ implementation of WeldDefaultProxyServices. The Jakarta Servlet-API classes are provided by Tomcat, and therefore have a classloader (and also a Lookup) which does not have access to the Weld classes. This results in the ClassNotFoundError when trying to resolve Weld-Classes like WeldConstruct.
When I temporarily added the "old" pre-Java11 implementation of WeldDefaultProxyServices (with the deprecated "AccessController.doPrivileged" call, the injection still works (but obviously I don't want to use this solution for production, and it might be broken in future Java versions).
Full Stacktrace:
