## Install OpenJDK - OpenJRE v.8 for elasticsearch

# A few reasons for installing distribution-provided OpenJDK:
#
#  1. Oracle.  Licensing prevents us from redistributing the official JDK.
#
#  2. Compiling OpenJDK also requires the JDK to be installed, and it gets
#     really hairy.
#
#     For some sample build times, see Debian's buildd logs:
#       https://buildd.debian.org/status/logs.php?pkg=openjdk-8

# Default to UTF-8 file.encoding
ENV LANG C.UTF-8

# add a simple script that can auto-detect the appropriate JAVA_HOME value
# based on whether the JDK or only the JRE is installed
