------------------------------------------
Summary: Handle NoSuchFileException
Key: LUCENE-5550
URL: https://issues.apache.org/jira/browse/LUCENE-5550
Project: Lucene - Core
Issue Type: Bug
Reporter: Michael McCandless
Priority: Blocker
Fix For: 4.8
With Java 7 we now must handle either NoSuchFileException (thrown by nio) or
FileNotFoundException (thrown by pre-nio io apis) coming out of some Directory
methods.
We did this on trunk already but we need to do it for 4.x as well... including
fixing MockDirWrapper to randomly pick one to throw.
Uwe said:
I did a grep for NoSuchFileException on trunk and 4.x.
In trunk we have many more of this Excepotion, especially also randomization in
MockDirectory to throw this one or FNFE. We should backport those fixes:

This is important to fix before we release 4.8 for Java 7
