Aaron McCurry commented on BLUR-76:
-----------------------------------

This task has proven to be very difficult in Lucene 4.  So I'm going to move it 0.1.6.

> Currently the 0.1.5 warmup logic is very basic when compared to prior versions.  The
reason for the change it that the warmup logic is not compatible with Lucene 4 code.
> Basically the idea of the warmup is prefetch and populate the blockcache with preconfigured
fields, so that queries that involve those fields will be in memory.  The previous version
used reflection to access the terminfos in the segmentreaders to the positions in the various
files that needed to be read into memory on a field by field basis.  We need to figure out
how to do this in Lucene 4
