Test failures after migration to Jersey 3.1.1

[sergey-morenets]

Hi

We've just migrated from Jersey 3.0.3 to 3.1.1 and noticed that most of our Jersey-related integration tests started failing with 404 error.
Our investigation figured out that cause of this issue is this commit - a83c7cd

Previously Jersey Grizzly 2 container didn't use path value from @ApplicationPath so we provided "orders" relative path in the tests using WebTarget object.
But in Jersey 3.1.x application path is actually used:

final String appPath = handler.getApplicationHandler().getConfiguration().getApplicationPath();
final String uriPath = appPath == null ? uri.getPath() : uri.getPath() + "/" + appPath;

So we have to update tests and include application path: "api/orders".

This seems to be breaking change but it's never mentioned in the Jersey documentation ("Migration Guide" section) - https://eclipse-ee4j.github.io/jersey.github.io/documentation/latest31x/migration.html

It's more a fixed bug, Jersey 2.x and 3.0.x did not support @ApplicationPath by other then Servlet container, but they should have. Jersey 3.1 do implement it, but it was not backported to older versions, not to break anything.

Right, we should mention it in doc.
