Subject Re: Clustering error in Solr 8.2.0
Date Tue, 13 Aug 2019 07:38:13 GMT
For lingo3g, they have replaced commons-lang with commons-lang3 in version
1.16, which should be in line with what Solr has done.

Just that our lingo3g licence does not allow us to upgrade to the new
version 1.16, and if we stick to the older version 1.15.1, it requires the
use of commons-lang.

Regards,
Edwin
