# Install JBoss Developer Studio.  The needed files will be downloaded
# from the provided URL. The reason for this is to not include the
# JBDS distribution in the docker layer since this image is going to
# be quite large.  If the docker ADD instruction is used the file
# becomes a permanent part of that layer, bloating the size of an
# already large image.
#
# The for loops scan the JBDS installation for native libraries and
# then remove any that are already present in the system libraries.
# Redundant libraries that varied by version resulted in JBDS
# crashes.
#
# Finally, the last command installs the JBoss integration tooling.
