If executed in the UI thread, a long operation can freeze the UI.

• network operations
• database operations
• file operations
• etc.

Solution¶

If possible run operations within a JobHandler class (not in the UI thread)

JobHandler = new JobHandler("title") {
    @Override
    protected IStatus run(IProgressMonitor monitor) {

        // do something
        ...

        // do something in the UI thread
        this.syncExec(new Runnable() {
            @Override
            public void run() {
                ...
            }
        });

        return Status.OK_STATUS;
    }
}
