@Wendy just do the suggested solution:
db.default.maxConnectionAge=0
Not sure what positive affect db.default.maxConnectionAgeInSeconds would have given that Play effectively forces a timeout within 60 minutes with the under the hood maxConnectionAge default.
The above should solve the problem, seems to do so for everyone on Play 2.2.x using MySQL
