Hi All
Can I install 32 bit Jdk on 64 -bin Deoebian OS ?
I try to install openhab2 b3 but I have problem with Z-wave USB Stick ( I heard that is problem with serial devices in 64bit JDK )
I get
Linux debianpine64 3.10.101-4-pine64-longsleep #51 SMP PREEMPT Thu May 26 18:20:37 CEST 2016 aarch64 GNU/Linux
Regards

Another reason to take the 32 bit Oracle JDK: It is way faster than the 64 bit Oracle JDK, see
here:
Code:
# install the 64 bit Oracle JDK
sudo apt-get install oracle-java8-installer
# enable multiarch
sudo dpkg --add-architecture armhf
# install any 32 bit package in order to get the 32 bit libc, shared library loader, ... ,e.g.:
sudo apt-get install iperf:armhf
# install the 32 bit Oracle JDK in parallel
# download the armhf package (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)
sudo tar -C /usr/lib/jvm -xzvf <archive>
cd /usr/lib/jvm
sudo mv jdk1.8.0_91 jdk1.8.0_91.armhf
sudo mv java-8-oracle jdk1.8.0_91.arm64 && sudo ln -s jdk1.8.0_91.armhf java-8-oracle

FYI, the wiki now has images for openhab, running the 32-bit Oracle JVM.
