There are currently 2 almost identical versions of Exceptions::special_exception, one when a Throwable object already exists and one for paths that only have the exception class name as a symbol and an optional message.
Exception logging (i.e. -Xlog:exceptions) only emits a message for the first version.
Logging also does not note when an exception is converted to a pre-allocated exception due to the current thread not being able to call Java.

This issue exists to consolidate the 2 versions and improve the logging.
