The reason the arrayFormat method doesn't use the original exception's
message is that there's no placeholder (i.e. "{}") for it in the message
that it's formatting. However, the original exception message *is*
preserved in the stack-trace because the "initCause" method is invoked with
the original exception. Therefore, when the stack-trace of the returned
exception is printed the original exception's message should be printed
along with it.If you want a simple way to get this message I suggest using ExceptionUtils.getRootCauseMessage from Apache's Commons Lang 3 [1]. Hope that helps!
