> The code assumes that if resource variable is not null, then the corresponding file exists at that location. In fact, when the file doesn't exist, the method org.eclipse.core.internal.resources.Container.getFile(..) might still return a not-null value (see http://mobius.inria.fr/eclipse-doc/org/eclipse/core/resources/IContainer.html#getFile(org.eclipse.core.runtime.IPath)). As a result, a not-null file path will be passed to OpenFileActionUtils.elementInResource(..), and a FileNotFoundException will be thrown.
> * Note that my project contains more than one source folder. This issue may not happen on one-source-folder project.
