[ http://issues.apache.org/jira/browse/LUCENE-129?page=all ]
Michael McCandless resolved LUCENE-129.
---------------------------------------
Fix Version/s: 2.1
Resolution: Fixed
OK I've fixed all cases of finalize except for one under contrib
(contrib/memory/src/java/org/apache/lucene/index/memory/MemoryIndex.java) whose
comment was spooky to me:
// lucene >= 1.9 or lucene-1.4.3 with patch removing "final" in superclass
protected void finalize() {}
Thank you Esmond and sorry for the long delay!

> Key: LUCENE-129
> URL: http://issues.apache.org/jira/browse/LUCENE-129
> Project: Lucene - Java
> Issue Type: Bug
> Components: Other
> Affects Versions: unspecified
> Environment: Operating System: other
> Platform: All
> Reporter: Esmond Pitt
> Assigned To: Michael McCandless
> Priority: Minor
> Fix For: 2.1

> The canonical form of a Java finalizer is:
> protected void finalize() throws Throwable()
> {
> try
> {
> // ... local code to finalize this class
> }
> catch (Throwable t)
> {
> }
> super.finalize(); // finalize base class.
> }
> The finalizers in IndexReader, IndexWriter, and FSDirectory don't conform.
> This
> is probably minor or null in effect, but the principle is important.
> As a matter of fact FSDirectory.finaliz() is entirely redundant and could be
> removed, as it doesn't do anything that RandomAccessFile.finalize would do
> automatically.
