> The tests change a final field value. In such a situation, the corresponding IgniteTestUtils method changes the corresponding Field's {{modifiers}} to remove the {{final}} flag from them. The modifiers are changed through a MethodHandle, and on highest Java versions, a MethodHandle of a final Field now throws an UnsupportedOperationException.
> It turns out, this modification of the modifiers is actually not needed on any of the currently LTS Java versions (11, 17, 21), so we can just remove this.
