You probably should add Jansi or JNA lib in your class path. See JLine README:

"On the Windows platform, relying on native calls is mandatory, so you need to have either Jansi or JNA library in your classpath along with the jline-terminal-jansi or jline-terminal-jna jar. Failing to do so will create a dumb terminal with no advanced capabilities."

Stackoverflow when using dumb terminal has been fixed in commit bb5e85a. You should use JLine version 3.18.0 or greater.

Thank you very much. The problem was solved after I upgraded the jline version.
