An interesting article from a person known to lucene-dev:
http://www-106.ibm.com/developerworks/library/j-jtp01274.html
I only skimmed the article, and only read the section about
finalizeable objects.
Lucene has several:
$ ffjg finalize
./index/IndexWriter.java: protected void finalize() throws IOException
{
./index/IndexReader.java: protected final void finalize() throws
IOException {
./store/FSDirectory.java: protected final void finalize() throws
IOException {
./store/FSDirectory.java: protected final void finalize() throws
IOException {
Then I read the following, and noticed the
"FinalizeDoesNotCallSuperFinalize" rule:
http://pmd.sourceforge.net/rules/finalizers.html
Then I looked at Lucene's finalize() methods and noticed that none of
them call super.finalize().
Now I'm wondering if they should.
I don't know enough about it to make strong statements, only point this
out to those who may know more, and can offer advice.
