32-bit support is very useful for research purposes - I would definitely welcome having it back. Otherwise it means having to also have Java 6 available, just for testing purposes. I patched OSX build process a bit and I've got now a 32/64bits VM working on OpenJDK 7 : java -d32 -version openjdk version "1.7.0-jdk7u4-b21" OpenJDK Runtime Environment (build 1.7.0-jdk7u4-b21-20120423) OpenJDK Server VM (build 23.0-b21, mixed mode) java -d64 -version openjdk version "1.7.0-jdk7u4-b21" OpenJDK Runtime Environment (build 1.7.0-jdk7u4-b21-20120423) OpenJDK 64-Bit Server VM (build 23.0-b21, mixed mode) It was mainly uncomments of features already included in OpenJDK 7 trunk. Patch available here : http://openjdk-osx-build.googlecode.com/svn/trunk/patches-jdk7u-osx/universal-build.patch

I haven't tried this, but I noticed in jdk/src/macosx/bin/universal/jvm.cfg you have

-server KNOWN -client IGNORE

Should that be '-client KNOWN' ? I thought the 32-bit JVM is a client-tuned hotspot. I could be wrong, based on the output of 'java -d32 version'.
