corba, jaxp and jaxws compiled before jdk repository

[Erik Joelsson]

Those repos are indeed compiled before the jdk just like in the old 
build. As I understand it, jaxp and jaxws have historically been 
delivered to other places as well as the jdk, which forced them to be 
compatible with at least some earlier jdk version, so this wasn't an 
issue. I also understand nobody touches corba, which makes it a non 
issue too. We have not considered moving these builds as we haven't 
thought it a problem.

One way to solve this could be to leverage the GenStubs facility in 
langtools. Another would be to add these source dirs to the main jdk 
java compile line. I don't really like the second option though. In that 
case I would rather see the source being folded into the jdk repo 
instead of living in it's own repo.

In hotspot, all javacode is compiled with the javac from the bootjdk as 
far as I know, so in that respect there is no dependency on the jdk 
being built.
