I had the same problem. I used the naive following code:
propval = System.getProperty (...) ;
if ( (propval != null) && (propval.equals ("true")) )
bool_property = true ;
else
bool_property = false ;
Although, I would very much like a standard way of getting at least
the basic types (Integer, Double, Real, String, Boolean, etc) from
properties.
