After an OS upgrade (and probably java upgrade), I am getting the following when running sexscripts. It does seem to work, but from the message that will change someday.

WARNING: An illegal reflective access operation has occurred

Groovy 2.4.12 should have been ok with that (breakage from Java 9). It means that Java 10 is not ok. I'll check this next week with a panel of Windows devices.
