Dmitriy Pavlov commented on IGNITE-11216:
-----------------------------------------
[~ustas], yes, warning about reflective access in unavoidable.
See also https://docs.oracle.com/en/java/javase/11/tools/java.html
--illegal-access and it's value 'permit'

This mode opens each package in each module in the run-time image to code in
all unnamed modules (such as code on the class path), if that package existed
in JDK 8. This enables both static access (for example, by compiled bytecode),
and deep reflective access through the platform's various reflection APIs. The
first reflective-access operation to any such package causes a warning to be
issued. However, no warnings are issued after the first occurrence. This single
warning describes how to enable further warnings. This mode is the default for
the current JDK but will change in a future release.
