Converts a ByteBuffer into an instance of class Class, with an optional CodeSource. Before the class can be used it must be resolved.

If a non-null CodeSource is supplied a ProtectionDomain is constructed and associated with the class being defined.

Parameters:

name     the expected name of the class, or null if not known, using '.' and not '/' as the separator and without a trailing ".class" suffix.

b     the bytes that make up the class data. The bytes from positions b.position() through b.position() + b.limit() -1 should have the format of a valid class file as defined by The Java™ Virtual Machine Specification.

cs     the associated CodeSource, or null if none

Returns: the Class object created from the data, and optional CodeSource.

Exceptions:

ClassFormatError if the data did not contain a valid class

SecurityException if an attempt is made to add this class to a package that contains classes that were signed by a different set of certificates than this class, or if the class name begins with "java.".
