List<ReferenceType> definedClasses();
Returns a list of all classes for which this class loader has been recorded as the initiating loader in the target VM. The list contains ReferenceTypes defined directly by this loader (as returned by definedClasses) and any types for which loading was delegated by this class loader to another class loader.
The visible class list has useful properties with respect to
the type namespace. A particular type name will occur at most
once in the list. Each field or variable declared with that
type name in a class defined by
this class loader must be resolved to that single type.
No ordering of the returned list is guaranteed.

for more information on the initiating classloader.
Note that unlike definedClasses() and VirtualMachine.allClasses(), some of the returned reference types may not be prepared. Attempts to perform some operations on unprepared reference types (e.g. fields()) will throw a ClassNotPreparedException. Use ReferenceType.isPrepared() to determine if a reference type is prepared.
Returns: a List of ReferenceType objects mirroring classes initiated by this class loader. The list has length 0 if no classes are visible to this classloader.
