When installing JDK it gives you option of installing demo's
which are precompiled, similarly for certain components like
jws, jnlp samples are there which are not pre-compiled and
lies under in separate folder{JAVA_HOME/sample}
These samples was added because of following ccc

But these samples are like demo only and user should have
control or option whether he wants them or no over his
system, Just like user have choice of opting for demo while
installation.

Suggestions:
We can make current "Demo" option in installer to look like
Demo/Sample
or we can make it "Examples" and in description we specify
will put demo and sample code.
