Hi Michael, I downgraded to Solr 4.4.0 and this issue is gone. No additional settings or tweaks are done.
This is not a fix or solution I guess but, in our case we wanted something working and we were running out of time. I will watch this thread if there are any suggestions but, possibly we will stay with 4.4.0 for sometime.
