The extended description ends with:
This package provides Java Development Tools, a complete and powerful
Java IDE along with several editors, a refactoring engine, Ant and
JUnit integration, debugger, and many more features.
A determiner is missing before "debugger", presumably "a".
By the way, the extended description of eclipse-platform-data needs to
be synchronized with eclipse-platform's.
This is the maintainer address of Debian's Java team
debian-j...@lists.debian.org for discussions and questions.
