Codereview request for 8006295: Base64.Decoder.wrap(java.io.InputStream) returns InputStream which throws unspecified IOException on attempt to decode invalid Base64 byte stream

[Xueming Shen]

Because the error is not really triggered by an io operation when
reading from the underlying input stream. Ideally it should be a
more specific "InvalidedBase64EncodingException" exception in
  this kinda of situation (like we we do for the decoder/encoder in
charset), but it is considered too heavy in Base64 class. Maybe
the word "obviously" in my email is not appropriate, it may be
more appropriate worded as "IAE is more appropriate than
IOE for ...".
