Uwe Schindler updated LUCENE-4440:
----------------------------------
Attachment: LUCENE-4440.patch
Patch adding the Exceptions to Codec and PostingsFormat.
The Analysis SPI factory loading mechanism does not have the chicken-egg
problem:
- It returns *new* instances and has no forName() method.
- Static class ctors from Subclasses are not executed while SPI loading, ass
SPIClassIterator does not initialize classes while loading. The first time a
factory is touched is when a new instance is created and that happens not while
SPI is initializing
Please check the messages, I want to commit this ASAP, because Robert wants to
spin a new RC.

> FilterCodec has a delegate() method through which an extension can return its
> delegate Codec. This method is called on every Codec method. Adrien, on
> LUCENE-4391, failed to pass a Codec in the ctor, since he couldn't called
> Codec.forName().
> Instead, we should just pass e.g. new Lucene40Codec(). I'll post a patch
> shortly.
