Re: .23 compile times
I've just done some tweaks in the POMs and I'm cutting the 8.30min full
dist build down to 3.45min. I'm removing all javadoc stuff from the dist
profile.

I think we should introduce a developer profile that does this.

Also, the 'mvn install -DskipTests', to get the JARs in your m2 cache is
taking 2mins. But we are building source JARs, the developer profile could
skip the generation of the source JARs, this would cut several seconds.

Finally, note that to just build all JARs 'mvn clean test -DskipTests' it
is taking 1.55mins.

If folk agree I'll open a JIRA to optmize the build based on these findings.

Thxs.

Alejandro
