----------------------------------
Summary: IndexReader close throwing NullPointerException
Key: LUCENE-4751
URL: https://issues.apache.org/jira/browse/LUCENE-4751
Project: Lucene - Core
Issue Type: Bug
Components: core/search
Affects Versions: 2.9.2
Environment: RedHat
Reporter: Anusha Rao
Hi,
Has anyone seen the NullPointerException as shown below before?
We have used Lucene to build a public site search functionality.
All the IndexReader objects in there are closed appropriately except one that
throws the following error and results in (too many files open) exception.
This brings the entire site down.
The lucene version we are using is lucene-core-2.9.2.jar
Any idea what could cause this exception?
java.lang.NullPointerException
