now i've found that, using the "$" symbol is optional. buf if you use it
on
a variable declaration, it's mandatory that you've to specify on further
reference of that variable. today's findings... :-)
In Java, '$' is valid in identifiers, just like a letter or '_'. Docs
explain that using the dollar sign may help you to distinguish between bound
variables and field names.
