Get one or more JavaSE Embedded 7 or 8 versions from http://www.oracle.com/technetwork/java/embedded/embedded-se/downloads/index.html. This needs license agreement and login to Oracle Network. Copy the archive file(s) to a folder named ./JavaVMs.
If you want to install the Unlimited JCE Policies, download them also from
UnlimitedJCEPolicyJDK7.zip: http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.htmljce_policy-8.zip: http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html and put them into./JavaVMsfolder.- If you want to increase installation time on host, you can generate JavaSE Embedded 8 jre-full version and put that as tar.gz file into
./JavaVMsfolder
Copy the folder ./JavaVMs to you target platform, e.g. Raspberry Pi.
scp JavaVMs/* pi@<ip>:/home/pi/jvm-perftest/JavaVMs
There is a helper script to install all JavaVM in folder ./JavaVMs on target platform. Set JAVA_HOME to an existing installation of JavaSE 7 or 8 (will be needed to create jre-full profile).
Sample for Raspberry Pi:
export JAVA_HOME=/usr/lib/jvm/jdk-8-oracle-arm-vfp-hflt
curl -s -o install-jvms.sh https://raw.githubusercontent.com/JochenHiller/jvm-perftests/master/scripts-common/install-jvms.sh
chmod u+x *.sh
./install-jvms.sh
For JavaSE Embedded 7 the archive file will simply be unpacked.
For JavaSE Embedded 8 and a pre-installed version the archive file will simply be unpacked.
For JavaSE Embedded 8 the archive file will be unpacked. The jrecreate.sh will be used to create a full-jre profile. The install folder will be the name of the VM extended by -jre-full.
If ZIP files present, the Unlimited JCE Policies will be installed into ../lib/security and will replace the original ones.
These JavaVMs are successfully running on Raspberry Pi. Soft-Floating versions are NOT supported due to missing OS support. See also https://community.oracle.com/thread/2473836. You can use pre-installed versions of jre-full version to minimize installation time on embedded device.

You can adapt the benchmark.sh to include all JVMs you want to test.
