Hi all, We don't have many statistics on the usage of our components as they are mainly consumed through Maven. There is an interesting metric that can be used to compare the components though, it's the Debian Popularity Contest [1]. It gives an indication on how many systems have the library installed.
Here is the summary for our components: logging 78878 collections3 76924 beanutils 75111 digester 74953 compress 73104 codec 18889 lang 15779 cli 13144 io 10791 pool 10235 dbcp 10172 el 5502 net2 4960 collections 3952 configuration 2972 jxpath 2805 validator 2674 daemon 2663 jexl 2110 vfs 1877 net1 1804 math 1741 modeler 1646 launcher 1393 fileupload 1026 discovery 860 lang3 358 attributes 358 jci 203 openpgp 155 csv 85 exec 85 javaflow 20 email 0 chain 0 dbutils 0 email, chain and dbutils are not packaged in Debian. As expected the usual suspects are on the top of the list, with some surprises though. I didn't expect compress to have such a high score for a rather young component.
