Compiling the DaCapo 9.12 Bach Benchmark Suite in Ubuntu 12.04

Update 26/05/2015. Thanks to Peter Hofer at JKU for a useful addendum regarding further problems!

Recently I’ve been doing some unusual memory management research using AspectJ. As part of this research, I’ve had to recompile the DaCapo 9.12 Benchmark Suite, which is the standard suite in memory management research.

In this post, I’ll explain how to do this. I built the suite on an Ubuntu 12.04, both 32-bit and 64-bit.

For the changes to files within the DaCapo file structure, I have created a patch for 64-bit compilation.

Installing Java

The first thing you’ll need to do is install three different versions of the Java SDK: 1.4, 1.5, and 1.6

These are available from the Oracle download archive:

The versions I installed were:

  • j2sdk1.4.2_19
  • jdk1.5.0_22
  • jdk1.6.0_45

If you have any problems installing the 64-bit versions, try using the 32-bit equivalent after installing ia32-libs using apt-get.

Assuming they’re in your ~/Downloads folder:

cd ~/Downloads
chmod +x j2sdk-1_4_2_19-linux-i586.bin jdk-1_5_0_22-linux-i586.bin jdk-6u45-linux-i586.bin

Then, one-by-one, run the scripts and agree to the license agreement:




The self-extracting binaries will have created subdirectories. These need to be moved:

sudo cp -r j2sdk1.4.2_19/ jdk1.5.0_22/ jdk1.6.0_45/ /usr/lib/jvm

Now configure the java installs using update-alternatives:

 sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/j2sdk1.4.2_19/bin/java" 1
 sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.5.0_22/bin/java" 2
 sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.6.0_45/bin/java" 3
 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/j2sdk1.4.2_19/bin/javac" 1
 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.5.0_22/bin/javac" 2
 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.6.0_45/bin/javac" 3

Configuring Java

Note that you must have version 6 set as your default to compile the benchmarks, at least at the moment you initiate the build:

export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_45/

Installing Other Packages

You’ll want to install apache ant, subversion, cvs, javacc:

sudo apt-get install ant subversion cvs javacc

Downloading the DaCapo Source

Change to the directory you want to work within.

Download the source from:

Save it in the working directory.


Configuring Ant Build Properties

Copy “” to “”:

cd benchmarks

Edit and add:




The failonerror property is useful for debugging.

Fix some Build Files


Fix the Eclipse URL in bms/eclipse/build.xml


Fix the svn repo URL in bms/jython/build.xml


Daytrader requires Java 1.5, but the rest of the suite uses 1.6. To get around this problem, follow the instructions as advised by Diogenes Nunez on the DaCapo mailing list.

[Updated 26/05/2015 – thanks to Peter Hofer]

The Daytrader benchmarks are built with Maven, which tries to download artifacts from repositories at Unfortunately, Codehaus is shutting down their services, and instead of serving HTTP 404 for the missing artifacts, their web server serves an HTML page which Maven happily accepts as POM and JAR file content. Obviously, this causes the build to fail. Since I could not find a way to prevent Maven from accessing specific repositories, I worked around this issue by adding the following to /etc/hosts:

Checksums for Jython and DayTrader

Remove the jython checksum file:

rm bms/jython/downloads/jython-src-svn-6571.tar.gz.MD5

Similarly, remove checksum for bms/libs/daytrader:

 rm libs/daytrader/downloads/geronimo-jetty6-minimal-2.1.4-plugins.tar.gz.MD5
 rm libs/daytrader/downloads/jstl-impl-1.2.jar.MD5
 rm libs/daytrader/downloads/daytrader-svn-767347-src.tar.gz.MD5


Info. from Peter Hofer:

“I encountered an error during the xalan build, where for a recursive invocation of ant, the environment variable ANT_HOME is set to the value of the “ant.install” ant variable. I had to explicitly set this ant variable with an additional entry in ant.install=/usr/share/ant”

Environmental Variables

Peter Hofer had some problems with his environment:

“Setting JAVA_HOME was not sufficient in my environment. I found that various other Java-related variables were pre-set in my openSUSE installation (JAVA_BINDIR, JAVA_ROOT, JDK_HOME, JRE_HOME) and at some point the build favoured one of those over JAVA_HOME, leading to errors, for example when starting Geronimo. After unsetting those other variables, the build completed successfully.”
