Bug 122577 Library Explorer does not refresh after creating or changing a library
1. Open the Library Explorer view. Create a library. Expected: The library appears in Library Explorer. Actual: The library does not appear in Library Explorer until you re-open Eclipse. 2. Open the Library Explorer view. Open an existing library. Change the library. For example, change the title, or add a report item. Save the library. Expected: The library changes appear in Library Explorer. Actual: The library changes do not appear in Library Explorer until you re-open Eclipse.
