"Application run failed" issue when upgrading from versions prior to 5.14
When upgrading License Statistics from version prior to 5.14, you might see following issue in core.log file when starting the application:
2019-04-19 19:40:44.964 | ERROR | main | o.s.b.SpringApplication | Application run failed(...)Caused by: com.mysql.cj.exceptions.CJCommunicationsException: The last packet successfully received from the server was 28,801,252 milliseconds ago. The last packet sent successfully to the server was 29,174,551 milliseconds ago. is longer than the server configured value of 'wait_timeout'.This problem is likely due to a lack of disk space for MySQL temporary files. MySQL uses the value of the TMPDIR environment variable as the path name of the directory in which to store temporary files. If TMPDIR is not set, MySQL uses the system default, which is usually /tmp, /var/tmp, or /usr/tmp.
To resolve this issue, increase the disk space for the tmp directory or use the "mysqld --tmpdir" option to specify a directory in a file system that has enough space.
