We build OracleJDK using DXSDK 2004. Building with a newer DXSDK may (in 
theory) cause some differences in  rendering graphics. Note that in 
practice I don't recall if anyone has ever seen any actual differences. 
However, when fixing e.g. 2D bugs, it is important that developers use 
the proper version of DXSDK for their developer builds to make sure they 
reproduce the actual issue. In all other cases the version of DXSDK 
doesn't really matter.

I don't see how this translates to DXSDK 2004 "being the only working 
directx sdk". I believe that the changes proposed by David are 
reasonable and should be implemented to allow the OpenJDK community 
build with any version of DXSDK.

I agree, this is a good idea. And this is exactly something that the 2D 
team should decide. However, I believe that the above patch could be 
applied to OpenJDK as an interim solution before the decision is made.
