Looking at the other report you mention (#563002) it appears that the
issue was bunted to aptitude.  It is actually the package relationships
in -3.5-java which are broken.  That package should either Breaks or
Conflicts with -3.4-java, and maybe Replaces also.

This is not so in Squeeze:
$ apt-cache show libswt-gtk-3.5-java
[…]
Version: 3.5.1-2.1
Depends: libswt-gtk-3.5-jni (= 3.5.1-2.1)
Suggests: libswt-gtk-3.5-java-gcj

In unstable there is an appropriate Conflicts.

Maintainers of the swt-gtk may like to close this immediately.
