I am not sure I understand your questions, maybe you can explain you
what you are trying to achieve and I can tell how to do it.

Few general comments

As I tried to explain in the hangout, proper incremental compilation
requires type reference information. Consider two classes, A and B
extends A, and C. When A.java changes, it is not enough to recompile
just this source, it is also necessary to recompile B.java. Javac does
not provide type reference information, so the only safe way to handle
any change is to recompile everything.

Eclipse JDT compiler is production ready and it produces spec-compliant
class files. I believe all eclipse ecosystem is built with this compiler
and I've seen many projects outside of eclipse use it too.

"Eclipse jdt" is a name of Eclipse project that produces Java
Development Tools (hence the name). Spec-compliant java compiler is one
of deliverables of this project.

Good Evening Igor-

Instead of implementing eclipe jdt for incremental java compilation is there:

1)any ability to refactor/reconfigure javac to read Last Modified Date of 
source file to enable incremental compilation?
2)any concerns over generated class files..are they the same?
any deltas ..if so ...what are they?
3)can we implement a static settings.xml or other static configuration file 
that manfred suggested for eclipse jdt?
4)any ability to switch compiler from javac to jdt as an attribute in 
maven-compiler-plugin?

Thanks for a great presentation on Maven Dev hangout
Martin
