Hello, I've setup my own branch (https://github.com/lburgazzoli/apache-camel/tree/CAMEL-10224-log4j2) were I'm doing some test to migrate to log4j2. So far migrating the properties was not an issue and automated through a script.
The following component can't be migrate as they have some code based on log4j: - camel-spark - camel-spark-rest - camel-sip - camel-hbase For other components I found that log4j.properties was used also to perform some test (i.e. a file to serve in jetty9). All the remaining component and caml-core have been tested an successfully migrated. I still need to migrate examples, tooling and so on. --- Luca Burgazzoli On Tue, Aug 2, 2016 at 10:10 PM, Matt Sicker <boa...@gmail.com> wrote: > We have a ticket to track migration issues: > https://issues.apache.org/jira/browse/LOG4J2-1473 > > On 2 August 2016 at 12:24, James Carman <ja...@carmanconsulting.com> wrote: > >> Now, that's a motivation I can get behind! :) >> >> >> On Tue, Aug 2, 2016 at 12:38 PM Matt Sicker <boa...@gmail.com> wrote: >> >> > Another motivation is that when Camel wants to work on JDK9 support, >> you'll >> > find that log4j 1.x doesn't work anymore. >> > >> > On 2 August 2016 at 11:21, Luca Burgazzoli <lburgazz...@gmail.com> >> wrote: >> > >> > > My only motivation was to keep the dependencies up to date >> > > >> > > --- >> > > Luca Burgazzoli >> > > >> > > >> > > On Tue, Aug 2, 2016 at 5:50 PM, James Carman < >> ja...@carmanconsulting.com >> > > >> > > wrote: >> > > > If it's only for test, what's the motivation?
