Orca screen reader with java swing application

Hi. My name is Artem, I am developing an accessibility IDE based on IntelliJ at JetBrains.
I'm having trouble getting screen reader accessibility of a java swing app running with AtkWrapper.
I see that AtkWrapper has loaded and is working. Internal accessibility methods like AccessibleContext.GetAccessibleName() are called, but Orca doesn't say anything in the test swing application window.
I start the application like this:
```shell
./build/linux-x86_64-server-release/images/jdk/bin/java -cp "build/tests:/home/user/dev/gnome/jawbuild/lib/jvm/java-17-openjdk-amd64/lib/java-atk-wrapper.jar" -Djava.library.path=/home/user/dev/gnome/jawbuild/lib -Djavax.accessibility.assistive_technologies=org.GNOME.Accessibility.AtkWrapper -Djavax.accessibility.screen_reader_present=true AccessibleJListTest
```
I'm using ubuntu 20.04 LTS and building AtkWrapper 0.38.0 from source, and openJDK 17.
Can you please tell me if this is a known issue or am I doing something wrong?
