project to reproduce

The BMP export of some diagram freeze the bundle in an endless loop.
Steps to reproduce:

1- Import the attached project
2- Open the only diagram
3- Click on export button on tabbar
4- Choose to export as BMP
5- Launch export.

Then the bundle freeze.

The problem is located in org.eclipse.swt.internal.image.WinBMPFileFormat.unloadDataNoCompression(ImageData, byte[], OutputStream);

The line int linesPerBuf = 32678 / bmpBpl produce 0 as result because bmpBpl is 37440.

So the loop for (int y = 0; y < image.height; y += linesPerBuf) can never increment y leading to an infinite loop.
