Java and JavaScript in the Database

The [getPropertyInfo() method|http://download.oracle.com/javase/6/docs/api/java/sql/Driver.html#getPropertyInfo(java.lang.String,%20java.util.Properties)] of a JDBC driver is meant to parse a given JDBC URL for all relevant information. However when I call it on the 11.2.0.2.0 version of the ojdbc5 driver, with this URL:

jdbc:oracle:thin:@myHost:666:mySID

... all I get are these properties (none of which are the host, port, or SID):

Why does the driver not provide these three basic properties? It works nicely with the jTDS driver for SQL Server, for example.
