installation of tomcat6 removes eclipse

Installing tomcat6 removed eclipse and eclipse dependancies. The removal seems to be caused by dependancies of tomcat6: tomcat6 requires tomcat6-common, which requires libtomcat6-java. It is this latter package (libtomcat6-java) which removes eclipse, eclipse-jdt, eclipse-pde, eclipse-platform, eclipse-platform-data, and libtomcat7-java. The last removed package (libtomcat7-java) makes sense, but removal of eclipse packages seems unwarranted.

Release: 12.10
Eclipse: 3.8.0~rc4-1ubuntu1

A brief summary of what happens:

sudo apt-get install tomcat6 tomcat6-admin tomcat6-common tomcat6-user tomcat6-docs tomcat6-examples

installs the packages plus libtomcat6-java and removes eclipse eclipse-jdt eclipse-pde eclipse-platform eclipse-platform-data

sudo apt-get install libtomcat6-java

installs the package and removes eclipse eclipse-jdt eclipse-pde eclipse-platform eclipse-platform-data

Perhaps related:

sudo apt-get remove libtomcat7-java

removes libtomcat7-java AND eclipse eclipse-jdt eclipse-pde eclipse-platform eclipse-platform-data
