Investigate and propose a fix for the following.

The IGB App "Merge Annotation Operation" is currently failing with IGB 9.1.0, even though it can be installed. The problem may be due to a change in the API or possibly an OSGi wiring issue.

The bug:

You execute the usual workflow to install the App to IGB 9.1.0. However, when you try to find the App's menu item under Annotations tab > Multi-Track Operations, it is not there.

To reproduce:

1) Launch IGB 9.1.0
2) Select Arabidopsis genome (click flower picture next to the Mona Lisa)
3) Observe Araport track loads (this is an annotations track)
4) Open another annotations track by selecting its checkbox in the Available Data Sets section (TAIR10 is fine)
5) Load some data for the new track by clicking "Load Data" button or by choosing "Genome" in the Load Mode menu in the Data Management Table.
6) Select Annotations Tab
7) Click "Select All"
8) Now check the Operations menus. If you have installed Merge Annotations Operator, there should be an option "Merge" in this menu.

To install the App:

1) Go to https://bitbucket.org/lorainelab/merge-annotation-operator/src/master/
2) Click Downloads link
3) Copy URL
4) Add this repository as a new App repository in IGB
5) Install the App (it should appear as a new App in the App Manager)
