WARNING: An illegal reflective access operation has occurred

[lowang]

when running my program using g419-liner2-cli-2.7.jar on openjdk 11.0.18 I've got following warnings while loading chunkers:

-> Setting up chunker: chunker_timex_norm_duration

As message says openjdk 17 is blocked by this.
I've spotted this warnings because my other deps can't run on jdk 8:
