I don't think Debian 10 "Buster" should include eclipse and swt-gtk if they haven't been upgraded past 3.8.
I came across this bug report while trying to remove the unsecure webkitgtk from Debian. webkitgtk is ready for removal from Debian Testing in 3 days except… libswt-webkit-gtk-3-jni has an undeclared dependency on libwebkitgtk-1.0-0 https://bugs.debian.org/879170 Once libwebkitgtk-1.0-0 is removed, the functionality provided by that library will be completely broken. It looks like it might be fixed by "simply" updating swt-gtk and eclipse to a newer version. Are there any objections to me requesting that the ftpmasters remove swt-gtk and eclipse from Debian Testing so that we can complete the webkitgtk removal from Testing? Thanks, Jeremy Bicha
