Moreover when using an official public jdk7 release as the jdk1.7.0_45 as the bootstrap jdk of jdk8, the produced jvm.vxproj does not work as the changeset associated with the JDK 8016019 are not back ported to the jdk1.7.0_45 release. So I am wondering what specific parameters hotspot developers are using to test their changes under WXP/W7 for the jdk8 hotspot?

The visual studio projects are not the official way to build hotspot. They are provided as a nice-to-have feature that developers on windows maintain. The official way to build on all platforms is to use the makefiles.
