Hi,
Sorry that I'm not familiar with emails and mailing lists, Please do
not hesitate to point out anything I've done wrong.
Recently I had some issues when using Maven. I have a module-info.java
with "uses" and "provides" statements in it. When I tried compiling,
the compilation would fail if the service and service implementation
classes declared in module-info.java had annotated type
parameters(e.g. method declaration like "void m(List<@Nullable String>
l);").
Here are the stacktraces:

The direct cause is QDox's parser bug, and here are the related issues:
https://github.com/paul-hammant/qdox/issues/182
https://github.com/paul-hammant/qdox/issues/181
I wonder why Maven would need to parse the module-info.java. Also, it
looks like that QDox is under inactive development, so I wonder if
there is any workaround.
Thanks.
