IndexWriter.getReader() allocates file handles
----------------------------------------------
Key: LUCENE-2255
URL: https://issues.apache.org/jira/browse/LUCENE-2255
Project: Lucene - Java
Issue Type: Bug
Components: Index
Environment: Ubuntu 9.10, Java 6
Reporter: Mikkel Kamstrup Erlandsen

I am not sure if this is a "bug" or really just me not reading the Javadocs
right...
The IR returned by IW.getReader() leaks file handles if you do not close() it,
leading to starvation of the available file handles/process. If it was clear
from the docs that this was a *new* reader and not some reference owned by the
writer then this would probably be ok. But as I read the docs the reader is
internally managed by the IW, which at first shot lead me to believe that I
shouldn't close it.
So perhaps the docs should be amended to clearly state that this is a
caller-owns reader that *must* be closed? Attaching a simple app that
illustrates the problem.
