CORBA generates quite a bit of code during the build, so just
compiling *.java
won't work at all there. There is no native code (except the CLI

Ken.
jaxp, jaxws, langtools directories are almost 100% java, and I don't
think need to generate any java code or rely on native code being
compiled, but
I'm not 100% sure of that.
But the jdk directory and it's makefiles are the ones that contain
the core
java sources, with some generated sources, and the native
compilation scattered
all around in it.
Historically in jdk6 and older source bases, the jdk directory
(formerly called
"j2se") was built in such a bootstrap way that it was necessary to
build all
the native code with the java classes so that the resulting classes
could actually
be run during the build.
With jdk7 this need to run what you built during the build has gone
away quite a bit
with the creation/separation of the langtools directory.
So it's becoming more possible to separate the build into phases
that could be
done to the complete source base, e.g. import_files, prep_tools,
generate_source,
compile_java_classes, create_javah_headers,
compile_native_code, ... etc.
I have no idea if this will ever happen, but it is now at least
possible.

Hi there,
I'm looking for a make target, that compiles only the Java classes of
OpenJDK. Is there a way to do that? Thanks,
