Subject Re: [jira] [Commented] (KARAF-3940) Make it possible / easy to configure which spring version Karaf uses
Date Thu, 20 Aug 2015 09:10:16 GMT
Jetty is way harder, as it's not really compatible. Especially with minor
version updates and sometimes with patchversions too. Though that should be
an issue of the past. The next thing that interferes with Jetty, each
Pax-Web Version is bound to some Jetty version, or better to some jetty
minor version.
For example Pax-Web 4.2.x is bound to jetty 9.2 while Pax-Web 6 is bound to
jetty 9.3 which again needs java8 ... and so on .. so that is a lot harder.
