При установке tomcat8 + openjdk из http://packages.lab50.net/se15/ при его старте наблюдаю следующие предупреждения:

конечно это не ошибки, но все таки

если папки можно и руками создать, то отсутствие commons-dbcp.jar и commons-pool.jar немного напрягает , хотя никак и не влияет на работу самого tomcat8

причем /usr/share/tomcat8/lib/commons-pool.jar и /usr/share/tomcat8/lib/commons-dbcp.jar являются ссылками на /usr/share/java/commons-pool.jar и /usr/share/java/commons-dbcp.jar соответственно

поиск

dpkg -S commons-pool.jar

tomcat8-common: /usr/share/tomcat8/lib/commons-pool.jar

т.е. не могу понять к какому пакету относятся эти файлы, так как все зависимости при установке соблюдены
