Mime decoder does not ignore non-Base64 chars that appear after padding ('=')

import java.util.Base64;

public class CharToIgnoreAtTheEnd {

    public static void main(String[] args) {
        Base64.getMimeDecoder().decode("bGVhc3VyZS4=$");
    }
}

The output is 

Exception in thread "main" java.lang.IllegalArgumentException: Input byte array has wrong 4-byte ending unit
	at java.util.Base64$Decoder.decode0(Base64.java:1080)
	at java.util.Base64$Decoder.decode(Base64.java:686)
	at java.util.Base64$Decoder.decode(Base64.java:709)
	at CharToIgnoreAtTheEnd.main(CharToIgnoreAtTheEnd.java:6)


The following JCK tests will fail due to this issue:

issue still exists in b78

Still getting IAE with b78 --- import java.nio.charset.StandardCharsets; import java.util.Base64; public class OutByteArrayIsTooSmall { public static void main(String[] args) { final byte[] expected = "fo".getBytes(StandardCharsets.US_ASCII); byte[] dst = new byte[expected.length]; Base64.getMimeDecoder().decode("Zm8=\r\n".getBytes(StandardCharsets.US_ASCII), dst); } } --- Exception in thread "main" java.lang.IllegalArgumentException: Output byte array is too small for decoding all input bytes at java.util.Base64$Decoder.decode(Base64.java:749) at OutByteArrayIsTooSmall.main(OutByteArrayIsTooSmall.java:9)

It's a dup of 8006530. The latest push has fixed this issue (to ignore any non-base64 characters after padding character '=', if it's a MIME decoder)
