[ https://issues.apache.org/jira/browse/DBCP-316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796493#action_12796493 ]
Phil Steitz commented on DBCP-316:
----------------------------------
Agree this is a needless check

> Key: DBCP-316
> URL: https://issues.apache.org/jira/browse/DBCP-316
> Project: Commons Dbcp
> Issue Type: Bug
> Reporter: Sebb
>
> datasources.SharedPoolDataSource.getPooledConnectionAndInfo() contains an impossible null check:
> {code}
> synchronized (userKeys) {
> key = getUserPassKey(username, password);
> }
>
> try {
> info = (PooledConnectionAndInfo) pool.borrowObject(key);
> }
> catch (SQLException ex) { // Remove bad UserPassKey
> if (userKeys != null) { // <== cannot be null here, else synch. would have failed with NPE
> ...
> {code}
> The null check should be removed, as userKeys cannot be null (it is a final variable, and set non-null).
