Hey Shawn,
i removed the additional jars and tried the foreground option with the
following result:

There is absolutely no clue about whats going on.
Regarding the rollover size. I was just playing around to see if the rollover
works as I expected.
Thanks,
Michael

As Varun said, jackson is already included in Solr. You won't need to add any
jars for that.

Start Solr in the foreground, with the -f option. This will cause Solr to log
to the console. When Solr is started in the background, it suppresses console
logging.
I see that you have changed the logfile rollover size to 1MB. If your Solr
server sees much traffic, this is going to result in an extremely fast
rollover, which may mean that you lose access to logged events VERY quickly.
This will especially be the case with JSON logging -- each event will take up a
lot more space.
Thanks,
Shawn
