# In addition to installing the Amazon corretto, we also install
# fontconfig. The folks who manage the docker hub's
# official image library have found that font management
# is a common usecase, and painpoint, and have
# recommended that Java images include font support.

# The logic and code related to Fingerprint is contributed by @tianon in a Github PR's Conversation
