What are the new changes in Apache POI 3.9 ? Memory leakage issue in 3.9?

Question

In Apache POI 3.9 version release they are telling the memory leak and creating temp file is fixed (bug : 53493). But how to use that? Is there any changes for the importing packages in 3.9 version compared to 3.8? If the changes occur, then what are they?

Answer 1

The change log for Apache POI is available online. To see the changes between 3.8 and 3.9, look between here and here

Unless otherwise detailed in the release notes included in the download, you should be fine to just drop the new jars in, in place of the old ones. Make sure you really remove the old ones though! You get all sorts of odd things going wrong if you have both old and new POI jars on your classpath
