ResultRset get<Number> throws NullPointerException if the cell is empty

[GoogleCodeExporter]

Any empty cell  withResultSet.get<Number> methods (e.g. getInt(), getFloat(), 
...).

In JDBC with real database return zero value not throwing NullPointerException 
or return null value.

It seems it can be fixed by simplely check "cell.doubleValue == null" in 
get<Number> methods like this:

return (<type>) ((cell == null) ? 0.0D : cell.doubleValue.doubleValue());
  --> 
return (<type>) ((cell == null || cell.doubleValue == null) ? 0.0D : 
cell.doubleValue.doubleValue());
