betwixt warnings in publishing logs

Seeing allot of warnings / spurious info related to Betwixt in a client’s publishing logs. Has anyone else run into this? I am trying to determine if something is mis-configured or what.

[org.apache.commons.betwixt.io.BeanReader] Could not create instance of type: org.apache.commons.jexl.Script
[org.apache.commons.betwixt.io.BeanReader] Cannot pop options off empty stack
[org.apache.commons.betwixt.io.BeanReader] Cannot pop options off empty stack
[org.apache.commons.betwixt.io.BeanReader] Cannot pop options off empty stack
[org.apache.commons.betwixt.io.BeanReader] Cannot pop options off empty stack
[org.apache.commons.betwixt.digester.ElementRule] No name attribute has been specified. This element will be polymorphic.

Thanks,

The first msg doesn’t look familiar to me, but the others I’ve seen many times in other contexts. Don’t recall seeing them in a pub log before. What is the level for each of them (i.e. INFO, WARN, etc?)
