My Code:

public static void openClassFile(String locationString) {
IWorkbench workbench = PlatformUI.getWorkbench();
workbench.getDisplay().asyncExec(new Runnable() {
public void run() {

IPath p = new Path(locationString);
IWorkspace workspace = ResourcesPlugin.getWorkspace();

if (workspace == null ) {
JOptionPane.showMessageDialog(null,"null workspace");
IWorkspaceRoot workspaceRoot = workspace.getRoot();
if (workspaceRoot == null ) {
JOptionPane.showMessageDialog(null,"null workspaceRoot");
JOptionPane.showMessageDialog(null,"before getFileForLocation");
IFile file = workspaceRoot.getFile(p);
FileEditorInput input = new FileEditorInput(file);
IWorkbenchWindow window = workbench.getActiveWorkbenchWindow();
IWorkbenchPage activePage = window.getActivePage();
if (null != activePage) {
try {
activePage.openEditor(input, "bndtools.bndWorkspaceConfigEditor", true);
} catch (PartInitException ex) {
JOptionPane.showMessageDialog(null,"Unable to open editor");
//ErrorDialog.openError(getSection().getShell(), "Error", "Unable to open editor", ex.getStatus());
} else {
JOptionPane.showMessageDialog(null,"No activePage");

I can see popup of "before getFileForLocation"; but I can't see the next popup which is supposed to display the file name:

Using the Java debugger you can probably find the answer to your question.

To learn about the Java debugger, look at the Eclipse documentation and tutorials, some examples:

Odds are it is related to using Swing controls while SWT is also running in-process.
