> MyClass is in a jar which is added to the classpath of the Process Project. Saving throws an event loop exception in Error Log View with the following stack.
> Caused by: org.eclipse.jface.util.Assert$AssertionFailedException: null argument;

> at org.eclipse.jface.util.Assert.isNotNull(Assert.java:126)

> at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35)
> at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:123)
> The problem is, that DeploymentForm.getElementsToCheckFor() does not respect that MyClass returns null for getCompilationUnit(). As a consequence, setCheckedElements is called with null in the Object[].
