Exactly.

What do I need to do to restore my LibreOffice ability to use the NLP > again ? Fix the Linux kernel and/or Java. Or use amd64 instead of i386. This is a know problem and doesn't happen on amd64. See #865303 [G|u|=☣] [src:linux] libreoffice: Libreoffice Java features crash with Linux 3.16.43-2+deb8u1 (and the bugs merged with it) #876051 [i|+|☣] [openjdk-8-jre-headless] i386 applications using JNI may crash due to Hotspot workaround for Exec Shield #876068 [i|+|☣] [openjdk-7-jre-headless] i386 applications using JNI may crash due to Hotspot workaround for Exec Shield and #876069 [i|+|☺☣] [openjdk-9-jre-headless] i386 applications using JNI may crash due to Hotspot workaround for Exec Shield (I just noticed that this fixed, not available in stable yet. Maybe I should force that newe(er) OpenJDK 9 for i386 for buster/sid/stretch-backports if it's available there.)
