JVM now compiles with Sun Studio on Linux
Yep, you heard it right.
The OpenJDK team has pulled off yet another fantastic feat here: http://hg.openjdk.java.net/jdk7/jdk7/hotspot/rev/485d403e94e1.
Serguei Spitsyn integrated recently into this changeset.

So, should we get excited about compiling OpenJDK/HotSpot? Doesnt Sun Studio on Linux already compile a bunch of industrial scale applications?
Indeed we should. Some reasons why:

HotSpot is a very non-trivial piece of C++ code, so getting it to compile and optimize isnt easy.
This work happened with collab between the Sun Studio QA team and the OpenJDK team.
HotSpot had never compiled with Sun Studio before and its Linux code was full of GCCisms. Doling the change to allow this compilation path improves the code quality of OpenJDK.
This opens the door to other things on Linux: dbx, NB-IDE, Performance Analyzer, Dtrace GUI and other tools to work with this.

IMO, the next logical step is to get OpenJDK projects within NetBeans (Sun Studio) IDE so OpenJDK developers can use a real IDE for development.

As Kelly Ohair mentions in his blog , it opens up new doors for both the Sun Studio and for OpenJDK teams.
