# Set JAVACFLAGS (used in the relevant javac lines in our Makefiles)
# so that any compiled Java code is backwards compatible with Java v1.8

# To fully support backward compatible compilation need to specfiy
# -bootclasspath in addition to -source and -target

# Note: Given the way autoconf/configure uses 'eval' to test for
#       javac, then the usual technique of double-quoting (e.g.) the
#       bootclasspath directory to project against spaces *doesn't*
#       *work* as in an eval it is not passed to a shell environment
#       to be interpretted first.  The main outcome of all of this
#       is that we need to resort to backlash escaping any spaces
#       to keep things on track
