[jira] Commented: (LUCENE-793) Javadocs should explain possible causes for IOExceptions

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/LUCENE-793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12469819 ] 

Doug Cutting commented on LUCENE-793:
-------------------------------------

Should we add more precise exceptions for these cases, and add them to the 'throws' for these methods?  If we make these subclasses of IOException then this would be back-compatible.

> Most methods in Lucene reserve the right to throw an IOException.  This can occur for nearly all methods from low level problems like wrong permissions, transient IO errors, bad hard drive or corrupted file system, corrupted index, etc, but for some methods there are also more interesting causes that we should try to document.
