Addendum: Downgraded to these:
libatk-bridge2.0-0_2.14.0-2_amd64.deb libatk-wrapper-java_0.30.5-1_all.deb libatk-wrapper-java-jni_0.30.5-1_amd64.deb and installed that (incidentally, there's no debug library for the 2.20.1-3 version that would really need one): libatk-bridge2.0-0-dbg_2.14.0-2_amd64.deb Now Java works again. So the (GRAVE!) bug is most probably either here https://bugs.debian.org/cgi-bin/pkgreport.cgi?package=libatk-bridge2.0-0 or here: https://bugs.debian.org/cgi-bin/pkgreport.cgi?package=libatk-wrapper-java Either way, the accessibility-team is responsible.
