    I had the same issue and fixed it by installing the 32 bit version of Eclipse Helios.

    Use:
    http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/helios/SR2/eclipse-jee-helios-SR2-macosx-cocoa.tar.gz

    Instead of:
    http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/helios/SR2/eclipse-jee-helios-SR2-macosx-cocoa-x86_64.tar.gz
