Noble Paul commented on SOLR-914:
---------------------------------
bq.Logging a warning seems like the right way to go to me
so do you mean , logging a warning and do not do cleanup. or log a warning and
do the cleanup ?
I would prefer the latter because the system will continue to work
> Presence of finalize() in the codebase

> There seems to be a number of classes - that implement finalize() method.
> Given that it is perfectly ok for a Java VM to not to call it - may be -
> there has to some other way { try .. finally - when they are created to
> destroy them } to destroy them and the presence of finalize() method , (
> depending on implementation ) might not serve what we want and in some cases
> can end up delaying the gc process, depending on the algorithms.
> $ find . -name *.java | xargs grep finalize
> ./contrib/dataimporthandler/src/main/java/org/apache/solr/handler/dataimport/JdbcDataSource.java:
> protected void finalize() {
> ./src/java/org/apache/solr/update/SolrIndexWriter.java: protected void
> finalize() {
> ./src/java/org/apache/solr/core/CoreContainer.java: protected void
> finalize() {
> ./src/java/org/apache/solr/core/SolrCore.java: protected void finalize() {
> ./src/common/org/apache/solr/common/util/ConcurrentLRUCache.java: protected
> void finalize() throws Throwable {
> May be we need to revisit these occurences from a design perspective to see
> if they are necessary / if there is an alternate way of managing guaranteed
> destruction of resources.
