Compiling ... messages

[Alan Bateman]

A minor comment but when compiling the native code in the jdk repository 
then the "Compiling ..." messages only print the file name so it's not 
obvious what code is being compiled (unless there is a warning or an 
error, in which case the full path is revealed). When compiling hotspot 
then the messages have the full path which is much clearer in my view.

Another thing that would be helpful is the compilation of the launchers 
where the build emits messages like this:

Compiling main.c
Compiling main.c
Compiling main.c
Compiling main.c
Compiling main.c
Compiling main.c
Compiling main.c
Compiling main.c
Compiling main.c
Compiling main.c
:

I can imagine this confusing new people and maybe it would be useful to 
include the launcher name in the messages.
