OpenJDK 8 packages with bad version numbers (8.u20.b23) were pushed to [testing]. New packages are now available (8.u11). Unfortunatly as new package version is lower than the faulty one, pacman should yield the following when updating: warning: jdk8-openjdk: local (8.u20.b23-1) is newer than testing (8.u11-1) warning: jre8-openjdk: local (8.u20.b23-1) is newer than testing (8.u11-1) warning: jre8-openjdk-headless: local (8.u20.b23-1) is newer than testing (8.u11-1) To sort this out, please manually install all 3 packages: # pacman -S jre8-openjdk jre8-openjdk-headless jdk8-openjdk warning: downgrading package jre8-openjdk (8.u20.b23-1 => 8.u11-1) warning: downgrading package jre8-openjdk-headless (8.u20.b23-1 => 8.u11-1) warning: downgrading package jdk8-openjdk (8.u20.b23-1 => 8.u11-1) resolving dependencies... looking for inter-conflicts...
