Confluence upgrade process should not chown/chmod hidden folders

The .bin upgrader executes the following commands on the Confluence home area as part of it's upgrade process:

chown -R "$username" "$1"
chmod -R og-rwx "$1"

Our home area has a hidden ".snapshot" subdirectory which contains weeks of snapshots which explodes the amount of time it takes to run the upgrade process.

Some solutions:
1.

chown "$username" "$1"
chown -R "$username" "$1"/*
chmod go-rwx "$1"
chmod -R og-rwx "$1"/*

2.
Use find with -prune to exclude certain directories supplied by the user prior to the upgrade.
