Description

Description

#14583 only bumps the dependency and regenerates, but doesn't take advantage of the new features. I think we are currently taking care of this with skeleton files in gradle/generation/jflex. Using the builtin functionality might be cleaner.

Contributor guide

Research direction
Examine the JFlex 1.9.x release notes and changes to buffer size/expansion, compare with current skeleton files in gradle/generation/jflex, and determine if builtin functionality can replace custom skeletons.
