---------------------------------------

Hi [~oobles] you can use "@" mention when you need feedback from specific 
person/people to gain the attention (and sorry, I seem not to be the one here).

[~uschindler] would you give some feedback or thoughts.

Apologies that the commit is difficult to review. I staged the changes and 
moves in one commit when I should have done it as moves then changes. Let me 
know if you'd rather I redo it.

I'm not sure what is the preferred way, but you could make some small, 
incomplete patch/PR to describe your idea for review. Or I think some detailed 
design discussion (without patch) would also be okay before touching the 
codebase, since the problem you picked up would not be about java 
implementation, but package/module structure. ?

> To allow Lucene to be modularised there are a few preparatory tasks to be 
> completed prior to this being possible.  The Java module system requires that 
> jars do not use the same package name in different jars.  The lucene-core and 
> lucene-analyzers-common both share the package 
> org.apache.lucene.analysis.standard.
> Possible resolutions to this issue are discussed by Uwe on the mailing list

> {quote}About StandardAnalyzer: Unfortunately I aggressively complained a 
> while back when Mike McCandless wanted to move standard analyzer out of the 
> analysis package into core (“for convenience”). This was a bad step, and IMHO 
> we should revert that or completely rename the packages and everything. The 
> problem here is: As the analysis services are only part of lucene-analyzers, 
> we had to leave the factory classes there, but move the implementation 
> classes in core. The package has to be the same. The only way around that is 
> to move the analysis factory framework also to core (I would not be against 
> that). This would include all factory base classes and the service loading 
> stuff. Then we can move standard analyzer and some of the filters/tokenizers 
> including their factories to core an that problem would be solved.
> {quote}
> There are two options here, either move factory framework into core or revert 
> StandardAnalyzer back to lucene-analyzers.  In the email, the solution lands 
> on reverting back as per the task list:

> SPI to core / remove StandardAnalyzer and related classes out of core back to
