Error trapping in executeBatch (JDBC 3.6.20.1)

[GoogleCodeExporter]

Please describe a summary of the new feature (in a paragraph):
When an error occurs during a JDBC batch processing, there is no way to get the 
failed query.
The reason is that the method executeBatch (Stmt.java) does not tags the array 
of changes if an exception is rise by db.executeUpdate();
I suggest to add changes[i] = Statement.EXECUTE_FAILED before to throw a 
BatchUpdateException:
try {
      this.sql = (String) batch[i];
      db.prepare(this);
      changes[i] = db.executeUpdate(this, null);
      }
catch (SQLException e) {
      changes[i] = Statement.EXECUTE_FAILED // SUGGESTION HERE
      throw new BatchUpdateException("batch entry " + i + ": " +  e.getMessage(), changes);
      }
      finally {
      db.finalize(this);
      }

Please provide any additional information below:
