Jasper throws Java Heap Error

Hi all,

Recently I had some troubles heap error with Jasper Library in a Struts2 project.

In the first moment I think that is a issue with generation way and report size, but in some cases I checked the issue with one page report.

Somehow when the option "Stretch with Overflow" is set in a data field nearest the bottom of detail´s band and when all band´s size fill the page size causes the issue.

Steps to reproduce:

- Create a Jasper report in iReport;

- Set all the bands height to fill the max paper size;

- Create a text data field;

- Move the data field to nearest as you can to detail band´s bottom;

- Set the option "Stretch With Overflow" to this field (Like print screen attached);

- Set the Data linked to field to contains more characters that preset size (To force Overflow);

- Run preview and wait for Java Heap allocation Error;

Thanks in advance
