Description

Replace AnonymousXXXX classes inhereted from JLCA which make the code impossible to read.
Follow Digy's template to replace the single abstract method with Func<> or Action<>

like in FilterCache<T> from:
protected abstract object MergeDeletes(IndexReader reader, object value);
to:
Func<IndexReader, object, object> MergeDeletes;

Determine a solution to the classes with more than 1 abstract method without diverging much from Java.
