Oracle Java 7 release support both -d32 and -d64 in command line but
still report a 64bits VM

java -d32 -version
java version "1.7.0_04-ea"
Java(TM) SE Runtime Environment (build 1.7.0_04-ea-b225)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b09, mixed mode)

OpenJDK 7 64bits didn't support -d32 by default (ie: in non universal mode)

I updated jvm.cfg under jre/lib/jvm.cfg and switching from -client
IGNORE to -client KNOWN but didn't see any changes
