Hi John!
I've started to test our pods against 3.1.3, and found this error after installing ccPoiTools and ccPoiToolsExt. I can't find any mention of "Cannot reflect lib:" errors in the SkyFoundry forum. All available SkySpark 3.1.3 patches have been installed (4 as of the writing of this post), running on a Windows 10 machine, and Java version (shown below). Let me know if you need anything else to help support troubleshooting!
