JDK-6999460 - Glassfish build with JDK 6 / 7 is 5x-10x slower on Windows than on Linux
Description
javac can report how long it takes as part of -verbose, but that generates a lot of other info as well as execution time.

We should make so that javac can report (just) its execution time in a way that can be grepped from a build log, for the benefit of computing that actual time used by javac in one or more compilations.
Comments
EVALUATION If necessary, use short term -XD switch. Long term, extend -verbose to be more lint-like, with optional suboptions like -verbose:time -verbose:classreader etc and -verbose == -verbose:all
