Hello!
I'm using JackRabbit 1.6.
My project works well when I save small documents into then repository. Last
time when I save a small TXT file after a 6M DOC file, I got the following
exceptions.

2010-1-9 18:20:06[ WARN](LazyTextExtractorField.java:94) Exception reading
value for field: Stream close
Several lines before, there is a log INFO line like this,
2010-1-9 18:19:54[ INFO](MultiIndex.java:1210) updating index with 1 nodes
from indexing queue.
I‘m wandering if it is caused by the indexing mechanism.
I knew that JackRabbit is not thread-safe, but how can I do the concurrency
control? In my case, the node.save function returned without indicating the
indexing still processing, how can I avoid these collision？
Anyone can help?
