JVM heap size adjustments

One day I hope to get some Jetty chops and deploy a custom container, but it's about all I can do to just keep up with IdP 3 for now. Having the default container ship with the product and not have to worry about it is essentially the only reason we were able to get it deployed successfully as quickly as we did. 

Thanks for confirming how to adjust the heap size in the default container.

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.
