JFace: AssertionFailedException: application not initialized [message #448615]

IŽm using JFace in a standalone application on a Mac and run into an
AssertionFailedException:
assertion failed: The application has not been initialized.

The application runs without any problems on Windows and most of the
application works on a Mac. I havenŽt succeeded yet in reproducing the
error in a snippet.

I tried -disableassertions and -disablesystemassertions but nothing
changed.
IŽm using an ApplicationWindow now, but nothing changed (previously i used
TreeViewer directly in a standard SWT shell).

Here is the stack trace:

org.eclipse.core.internal.runtime.AssertionFailedException: assertion
failed: The application has not been initialized.

Every exception that occurs in a standalone JFace application,
is accidentally converted in an AssertionFailedException, if you
use a runtime.jar version thatŽs too old.
(fortunately i found a description of this problem in Googles cache,
i didnŽt find a hint in the eclipse newsgroups).

I donŽt know in which version this was fixed, but at least 3.1M4 handles
exceptions correctly! :-)

It worked in Windows and didnŽt work on Mac because there is a different
behaviour for selection-change-event in a tree.
In Windows you always get a not empty array of selected TreeItems,
on a Mac this array can be empty!

Bye,
