Simon Willnauer updated LUCENE-3190:
------------------------------------
Attachment: LUCENE-3190.patch
here is a patch that prevent this assert when ram buffer is low compared to the
size of the documents we are indexing.
for "normal" setting the assert will be executed but for very lowish documents
we simply skip it entirely
