JVM heap size adjustments

I found it:

        <?if $(var.msitype) = "x86" ?>
        <CustomAction Id="SetJavaJvmMx" Property="JAVA_JVMMX" Value="#768" />
        <?else ?>
        <CustomAction Id="SetJavaJvmMx" Property="JAVA_JVMMX" Value="#1024" />
        <?endif ?>

1024 on x64, 768 on x86.

Memory of course is tricky, there's no one size fits all there, but if we concluded that our defaults were a disservice to the people who had deployed that variant, I think we'd just ship a X.X.X.N+1 installer version that adjusted them to deliver that change to people.
