Build error with javac Main not being found when building java.transaction module on Mac OS X

@Erik and everyone else,

<whacks head on desk>, my sincere apologies and thank you for your
patience!  Indeed the modules.xml file was out of date. My script which
executes 'hg update' each morning had been silently failing for some time.
This is a good lesson for the build guide though, I'll add a note to remind
people that once they clone the top level repository that they should also
hg update as well as ./get_source.sh.

I now have separate build errors (of course!), these ones seem a little
more genuine, around the compilation / linking of desktop code with Mac
native libs.  There are too many to list, but here's an example of one below

=======

Creating libjsound.dylib from 17 file(s)
In file included from /usr/include/dispatch/dispatch.h:51:0,
                 from
/System/Library/Frameworks/CoreFoundation.framework/Headers/CFStream.h:15,
                 from
/System/Library/Frameworks/CoreFoundation.framework/Headers/CFPropertyList.h:13,
                 from
/System/Library/Frameworks/CoreFoundation.framework/Headers/CoreFoundation.h:55,
                 from

                 from
/System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h:12,
                 from
/Users/karianna/Documents/workspace/AdoptOpenJDK_projects/jdk9/jdk/src/java.desktop/macosx/native/libosxapp/AWT_debug.h:29,
                 from
/Users/karianna/Documents/workspace/AdoptOpenJDK_projects/jdk9/jdk/src/java.desktop/macosx/native/libosxapp/AWT_debug.m:26:
/usr/include/dispatch/object.h:143:15: error: expected identifier or '('
before '^' token
 typedef void (^dispatch_block_t)(void);
               ^
/usr/include/dispatch/object.h:362:3: error: unknown type name
'dispatch_block_t'
   dispatch_block_t notification_block);
   ^

Is this perhaps me using an unsupported compiler?  My C/C++ toolchain is:

...
* Toolchain:      clang (clang/LLVM)
* C Compiler:     Version Apple LLVM version 6.0 (clang-600.0.56) (based on
LLVM 3.5svn) Target: x86_64-apple-darwin14.1.0 Thread model: posix (at
/usr/bin/clang)
* C++ Compiler:   Version Apple LLVM version 6.0 (clang-600.0.56) (based on
LLVM 3.5svn) Target: x86_64-apple-darwin14.1.0 Thread model: posix (at
/usr/bin/clang++)
...



Cheers,
Martijn
