This isn't an SWT forum. In the future, please post such questions on a forum specifically for SWT issues.
But to answer your question, there's a 99.9% chance this is because you're launching the process on SWT's UI thread. Similar to performing long-running tasks on Swing's EDT, this is a no-no. The SWT UI won't be able to repaint itself until after your process has finished. To remedy this, launch your process in a separate Thread.
