34:            	Boot this module with the given properties. Creates a module instance
35:            	that can be found using the findModule() methods of Monitor.
36:            	The module can only be found using one of these findModule() methods
37:            	once this method has returned.
38:            	<P>
39:            	An implementation's boot method can throw StandardException. If it
40:            	is thrown the module is not registered by the monitor and therefore cannot
41:            	be found through a findModule(). In this case the module's stop() method
42:            	is not called, thus throwing this exception must free up any
43:            	resources.
44:            	<P>
45:            	When create is true the contents of the properties object
46:            	will be written to the service.properties of the persistent
47:            	service. Thus any code that requires an entry in service.properties
48:            	must <B>explicitly</B> place the value in this properties set
49:            	using the put method.
50:            	<BR>
51:            	Typically the properties object contains one or more default
52:            	properties sets, which are not written out to service.properties.
53:            	These default sets are how callers modify the create process. In a
54:            	JDBC connection database create the first set of defaults is a properties
55:            	object that contains the attributes that were set on the jdbc:derby: URL.
56:            	This attributes properties set has the second default properties set as
57:            	its default. This set (which could be null) contains the properties
58:            	that the user set on their DriverManager.getConnection() call, and are thus
59:            	not owned by cloudscape code, and thus must not be modified by cloudscape
60:            	code.
61:            	<P>
62:            	When create is false the properties object contains all the properties
63:            	set in the service.properties file plus a <B>limited</B> number of
64:            	attributes from the JDBC URL attributes or connection properties set.
65:            	This avoids properties set by the user compromising the boot process.
66:            	An example of a property passed in from the JDBC world is the bootPassword
67:            	for encrypted databases.
68:
69:            	<P>
70:            	Code should not hold onto the passed in properties reference after boot time
71:            	as its contents may change underneath it. At least after the complete boot
72:            	is completed, the links to all the default sets will be removed.
73:
74:            	@exception StandardException Module cannot be started.
