# The detection of javac below can handle cases:
# - where javac is a symbolic link
# - where there is actually a chain of symbolic links
# - where there are relative symbolic links
# - where some links/files are not called javac (e.g. ecj)
# - where there are directory names including spaces
# Note: The code would be simpler if we could rely on
#       the existence of "readlink -f" but we can't.
