Luca,
This is not a known problem with DaCapo, so on the face of it, this
looks like a bug in your version of the VM (perhaps a bug in how you
built it).
FYI, we maintain 12 hourly performance regressions of a number of VMs
here:
http://dacapo.anu.edu.au/regression/perf/2006-10-MR2.html (the latest
DaCapo release)
and here:
http://dacapo.anu.edu.au/regression/perf/head.html (the current
DaCapo svn head).
If there is interest and I can find the time, I may add the OpenJDK
head to the list of tested benchmarks.
Cheers,
--Steve

Hi all,
I recently tried to execute the DaCapo benchmark on OpenJDK 7 and I
found that "bloat" benchmark fails with the following exception:
$ OpenJDK/jdk7/build/linux-i586/j2re-image/bin/java-jar
~/dacapo-2006-10-MR2.jar bloat

I really don't know if it's a DaCapo problem or if I missed
something in
the build process of OpenJDK. The version of the DaCapo is 2006-10-
MR2.
I built OpenJDK both using mercurial repository and source bundle, and
the build runs fine but when executing the benchmark the same error
come
up. These are the options I used for building OpenJDK 7:
LANG=C
FINDBUGS_HOME= <local path for findbugs>
ALT_BOOTDIR=/usr/lib/jvm/java-6-sun
ALT_BINARY_PLUGS_PATH= <local path for binary plugs>
ANT_HOME=/usr/share/ant
ARCH_DADA_MODEL=32
Here there are some information on my machine:
$ uname -a
Linux 2.6.24-21-generic #1 SMP Tue Aug 12 13:37:22 UTC 2008 i686 GNU/
Linux
Any clues? Can anybody confirm such error?
Thanks for your attention,
Luca
