There will be sub task for each package which is not covered at least by 80%
For each sub task you can:

• add new tests to increase coverage above 80%
• add new tests to increase coverage below 80% with comment why it's not possible to achieve 80%
• close the sub task with comment why it's not possible to cover it by tests so it should be excluded from the coverage report

See chapter How to get the latest code coverage in https://docs.jboss.org/display/SWSQE/Code+coverage+for+system+tests to generate the latest code coverage.
