java.util.Base64 mime decoder does not ignore illegal characters during decoding

    Details

    • Subcomponent:
    • CPU:
      x86_64
    • OS:
      linux_ubuntu

      Description

      FULL PRODUCT VERSION :
      java version "1.8.0_121"
      Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
      Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

      A DESCRIPTION OF THE PROBLEM :
      The specification for java.util.Base64 MIME decoder says: "All line separators or other characters not found in the base64 alphabet table are ignored in decoding operation." This does not hold for example for input "TQ=*" which throws the following exception:

      Exception in thread "main" java.lang.IllegalArgumentException: Input byte array has wrong 4-byte ending unit
      at java.util.Base64$Decoder.decode0(Base64.java:704)
      at java.util.Base64$Decoder.decode(Base64.java:526)
      at java.util.Base64$Decoder.decode(Base64.java:549)

      REGRESSION. Last worked in version 8u112
