Please, as noted I am using JDeveloper which shares no code and only
vague history with JBuilder some time in the distant past. :-) There
is quite a difference.*
It turns out that whilst JDeveloper appeared to be invoking the javac
process, it was instead using the new compiler API. It turns out this
might no be connected up correctly so that apt is not run. The
workaround it in the project settings to make sure set the compile to
run "Out of Process".
