Strengthen/Harden Fineract 1.x to LTS Version by Upgrading Java & Improving Code Coverage of Tests

Overview & Objectives: The Fineract 1.x code base powering Mifos X and dozen of cloud-based core banking and fintech solutions around the world supporting millions of clients is very robust and feature-rich. With the wide functional footprint, there comes greater complexity in the code that makes maintainability more difficult. Additionally, as new features have been added the test coverage hasn't been extended at the same rate. The combination of these multiple factors - a large and varied user base that is reliant upon this vast codebase, the high maintenance burden, the need for increased testing coverage, and the need for a stable point for migration to the new architecture - merits this very important project will consist of these major tasks, documented in the following issues:
Description:

• Update Java from Version 8 to 11 (https://issues.apache.org/jira/browse/FINERACT-846)
• Measure Existing Code Coverage of Tests and Improve to at least 50% and Reduce Execution time (https://issues.apache.org/jira/browse/FINERACT-713)
• Ensure Fineract Codebase should pass PMD, Findbugs and Checkstyle analysis (https://issues.apache.org/jira/browse/FINERACT-712)

Helpful Skills: Spring, Hibernate, REST, Java, SQL
Impact: Improved functionality and increased stability of the core Fineract platform
