Remove Unnecessary NULL check in FindSegmentsFile - cleanup
-----------------------------------------------------------
Key: LUCENE-1686
URL: https://issues.apache.org/jira/browse/LUCENE-1686
Project: Lucene - Java
Issue Type: Improvement
Reporter: Simon Willnauer
Fix For: 2.9, 3.0
Attachments: segments_info.patch
FindSegmentsFile accesses the member "directory" in line 579 while performing a
null check in 592. The null check is unnecessary as if directory is null line
579 would throw a NPE.
I removed the null check and made the member "directory" final. In addition I
added a null check in the constructor as If the value is null we should catch
it asap.
