Unable to promote Apex test class, where test coverage is spread between two Apex test classes

Unable to promote Apex test class, where test coverage is spread between two Apex test classes. The deployment takes longer period of time to even report a failure. Promotion goes into infinity loop.

Steps to reproduce the behavior:
1. Create a apex test class with two methods: **Method1** and **Method2**.
2. Create apex test **Test_Class_1** to test the **Method1** .
3. Create another apex test **Test_Class_2** to test **Method2** .
4. Create a work item, approve the workitem.
5. Promote the work item.
...

**Expected behavior**
Promotion should be successful.
