A DESCRIPTION OF THE PROBLEM :
Consider we have an annotation with target = TYPE_USE and retention = RUNTIME. Applying this annotation to a type argument makes it appear in bytecode. This annotation is also visible to annotation processor, when annotation processor parses symbol from source code. However, when annotation processor takes symbol from bytecode, it fails to parse corresponding annotation.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create annotation 'A' with target = TYPE_USE and retention = RUNTIME
2. Define a class (B) with method that returns something with annotation mentioned in type arguments, for example List<@A String>
3. Define another class (C) in another module that somehow references the class from the former step, for example, extends it.
4. Write annotation processor that walks classes transitively, scans their methods and tries to extract annotation 'A'.
5. Apply annotation processor to C.java with classpath containing B.class


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Annotation processor does not see occurrences of annotation 'A'
ACTUAL -
Annotation processor should see occurrences of annotation 'A'

---------- BEGIN SOURCE ----------
This issue is not possible to reproduce on a single source file. I did not find a way to attach an example, so I just published it here: https://teavm.org/tmp/annot-processor-issue.zip

Example produces three compiler messages, namely foo:List<*String>, bar:List<*String> and foo:List<String>. The latter is expected to contain '*' character, i.e. be equal to the first one.

CUSTOMER SUBMITTED WORKAROUND :
I created another annotation processor that walks types, collects annotations from types and writes them into json files near class file. Then, main annotation processor parses these json files to resolve annotations. However, when I switched build from IDEA JPS to Gradle, it turned out that this approach does not work anymore, since Gradle incremental compiler passes to APT symbols, parsed from class files, which breaks this workaround. So effectively there's no workaround available for my case anymore.

FREQUENCY : always
