Arch Linux

Description:

The pdfsam wrapper script tries to use OpenJDK 11 by prepending it to $PATH, but the location of the Java binaries has changed in version 11:

% pacman -Qlq jre8-openjdk-headless | grep '/java$'
/usr/lib/jvm/java-8-openjdk/jre/bin/java

% pacman -Qlq jre-openjdk-headless | grep '/java$'
/usr/lib/jvm/java-11-openjdk/bin/java


Additional info:

% pacman -Qi pdfsam
Name : pdfsam
Version : 4.0.1-1

% pacman -Qi jdk11-openjdk
Name : jdk-openjdk
Version : 11.0.2.u7-1


Steps to reproduce:

% pdfsam
Run with exported java-11-openjdk
