If HotSpot support MacOS X Universal build, may be I could find here
some support to fix a problem I get with my OpenJDK 7 universal build
when using 32bits supper (-d32) and server mode (no problem in client
mode).

It is easily reproducible :

- Install OpenJDK 7 (from jdk7u-dev built in universal mode) from my
googlecode site :

http://openjdk-osx-build.googlecode.com/files/OpenJDK-OSX-1.7-universal-u-jdk-jdk7u5-b30-20120621.dmg)

Then :

export JAVA_HOME=/Library/Java/JavaVirtualMachines/1.7.0u.jdk/Contents/Home

mkdir jenkins
cd jenkins
curl -L http://mirrors.jenkins-ci.org/war/latest/jenkins.war -o jenkins.war
mkdir data
export JENKINS_HOME=`pwd`/data
java -d32 -jar jenkins.war


And there is no problem using -d32 -client or -d64.

Any help from Hotspot guys will be very useful since this problem
prevent me to ask for universal patch to be reintroduce in OpenJDK 7
and 8.

Thanks
