# jdownloader-2 Dockerfile
#
# https://github.com/jlesage/docker-jdownloader-2
#
# NOTES:
#   - We are using JRE version 8 because recent versions are much bigger.
#   - JRE for ARM 32-bits on Alpine is very hard to get:
#     - The version in Alpine repo is very, very slow.
#     - The glibc version doesn't work well on Alpine with a compatibility
#       layer (gcompat or libc6-compat).  The `__xstat` symbol is missing and
#       implementing a wrapper is not straight-forward because the `struct stat`
#       is not constant across architectures (32/64 bits) and glibc/musl.
