may fail to clean up java.sql.Statement

Method com.hysoft.cache.mgmt.bulkload.DomLoad.getTotalNum(long, String) may fail to clean up java.sql.Statement

 

This method may fail to clean up (close, dispose of) a stream, database object, or other resource requiring an explicit cleanup operation.

In general, if a method opens a stream or other resource, the method should use a try/finally block to ensure that the stream or resource is cleaned up before the method returns.

This bug pattern is essentially the same as the OS_OPEN_STREAM and ODR_OPEN_DATABASE_RESOURCE bug patterns, but is based on a different (and hopefully better) static analysis technique. We are interested is getting feedback about the usefulness of this bug pattern. To send feedback, either:

• send email to [email protected]
• file a bug report: http://findbugs.sourceforge.net/reportingBugs.html

In particular, the false-positive suppression heuristics for this bug pattern have not been extensively tuned, so reports about false positives are helpful to us.

See Weimer and Necula, Finding and Preventing Run-Time Error Handling Mistakes, for a description of the analysis technique.

            LOG.info(e);
            e.printStackTrace();
        } finally {
            try {
                if (resultSet != null) {
                    resultSet.close();
                }
            } catch (SQLException e) {
                LOG.info(e);
                e.printStackTrace();
            }
           
            try {
                if (ps != null) {
                    ps.close();
                }
            } catch (SQLException e) {
                LOG.info(e);
                e.printStackTrace();
            }
           
            try {

                    connection.close();
                }
            } catch (SQLException e) {
