Comment 14 for bug 81876

the same,
apt-cache policy says:
Installato (installed, it has right dependencies): 1.2.1-3ubuntu1
Candidato (candidate): 1.2.1-4ubuntu1

Anyway, after some other research, I found that the problem of tomcat5.5 dependencies is not strictly correlated with this one, but on the ecj-bootstrap package which depends on others that needs ecj.
The problem is already on charge in other bug repert, so for me this problem is solved.

Sergey if you need install
Package: libcommons-dbcp-java
Version: 1.2.1-3ubuntu1

it has the right dependencies.

Bye and thanks for help and for working to help linux users
