RFR(M): 8165550: Add class loader names to ClassCastException message

[David Holmes]

Hi Rachel,

Just wondering, in the most complex case, exactly what will this new 
message look like? We seem to be including module names as well as 
classloader names, and of course class names.

Arguably we should only add the additional info when they differ between 
the types ie if both in same classloader and same module then only 
report class name; if same loader but different module report 
module:class; if different loaders then report everything 
loader:module:class. Also not sure module version is needed at all in 
this message.

Thanks,
David
