What do the errors caused by webclient mean?

We introduced a small webclient solution, but when I look into the serverlog: I see a lot of errors. (see attached)
Can anyone tell me what they mean?

The solution runs/behaves fine as far as I can see.

this is a debug info message somebody left into the wicket code.
I removed it and updated the wicket jars. For now those just can be ignored.

Any chance I can get the updated wicket jars and use them - safely - within my current 5.1.4 deployment?
Those errors are really distracting from the ones I really need to see…
