Apologies for cross posting to the dacapobench-researchers and

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
===== DaCapo bloat starting =====

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
