@Junior ,
You’re not the only one facing problems with Lucee 6.1.x.
I was unable to start Lucee Express 6.1.0.243. I have just downloaded Lucee Express 6.1.1.118 only to run into the exact same problem I faced with Lucee Express 6.1.0.243.
Besides, though Lucee Express 5.4.x is on Tomcat 9, it seems Lucee Express 6.1.1.118 has regressed to Tomcat 8.
