That is a bit inconvenient. Ubuntu provides 3.3 and 3.4, but not 3.2. Nevertheless, I'm sure I can find the source somewhere. > Treat hotspot separate, build it the way you want, and plug it into > the jdk image you want to use.

In the beginning, I could not get anything to work aside from the top level build system. Now I appear to be suitably equipped to type 'make' in hotspot/make, which is an improvement. Still, 'make profiled' is not valid, and 'make help' does not offer any advice on the topic. I am taunted by the 'profiled' target in the linux Makefile! >> What is the official way to build openjdk with profiling? > > As far as I know, there is none.
