> Move the static FieldCache.DEFAULT field instance to atomic IndexReaders, so that FieldCache
insanity caused by the WeakHashMap no longer occurs.
> * Add a new method to IndexReader that by default throws an UOE:
> {code}public FieldCache getFieldCache(){code}
> * The SegmentReader implements this method and returns its own internal FieldCache implementation.
This implementation just uses a HashMap<Entry<T>,Object>> to store entries.
> * The SlowMultiReaderWrapper implements this method as well and basically behaves the
same as the current FieldCacheImpl.
> This issue won't solve the insanity that comes from inconsistent usage of a single field
(for example retrieve both int[] and DocTermIndex for the same field).
