Message:

• Invoke 'readlink' with '-f' to recursively traverse symlinks.

When using "which java" to detect the location of the java binary on
platforms using the /etc/alternatives system to allow diversions,
multiple layers of symlinks may need to be traversed to ultimately get
to the desired binary. Use "readlink -f" to get to the canonical name
by following every symlink in every component of the path.

Thus:
$ which java
/usr/bin/java
$ readlink $(which java)
/etc/alternatives/java
$ readlink -f $(which java)
/usr/lib/jvm/java-7-oracle/jre/bin/java
