Hi, That’s related to the Pax Web 7.3 update we did for Karaf 4.3.0.
It upgraded to undertow. Here, you have two javax.servlet version: - 3.1.0 coming with pax-web-undertow - 4.0.0 coming with io.undertow.servlet As workaround you can blacklist javax.servlet 3.1.0 coming from pax-web-undertow. Anyway, for Karaf 4.3.1, I will fix that at Pax Web (with new 7.3.x version).
