> I am currently changing my code to be most compatible with 2.4. I switched on deprecation
warnings and got a warning about the autoCommit parameter in IndexWriter constructors.
> My code *should* use autoCommit=false, so I want to use the new semantics. The default
of IndexWriter is still autoCommit=true. My problem now: How to disable autoCommit whithout
deprecation warnings?
> Maybe, the "old" constructors, that are deprecated should use autoCommit=true. But there
are new constructors with this "IndexWriter.MaxFieldLength mfl" in it, that appear new in
2.4 but are deprecated:
> IndexWriter(Directory d, boolean autoCommit, Analyzer a, boolean create, IndexDeletionPolicy
deletionPolicy, IndexWriter.MaxFieldLength mfl) 
>           Deprecated. This will be removed in 3.0, when autoCommit will be hardwired
to false. Use IndexWriter(Directory,Analyzer,boolean,IndexDeletionPolicy,MaxFieldLength) instead,
and call commit() when needed.
> What the hell is meant by this, a new constructor that is deprecated? And the hint is
wrong. If I use the other constructor in the warning, I get autoCommit=true.
> There is something completely wrong.
> It should be clear, which constructors set autoCommit=true, which set it per default
to false (perhaps new ones), and the Deprecated text is wrong, if autoCommit does not default
to false.
