A DESCRIPTION OF THE REQUEST :

java.util.Base64.getUrlEncoder() should not apply padding at the end of encoding.

Alternatively, padding control should be exposed as an option. There are several variants of base64 encoding where padding should be omitted: http://en.wikipedia.org/wiki/Base64#Variants_summary_table


JUSTIFICATION :
This is a fairly common scenario. In base64url encoding padding is usually omitted. It is certainly optional and if present should actually be URL encoded as %3D.

Thus, the default behavior of Base64.getUrlEncoder should be changed to omit padding.




CUSTOMER SUBMITTED WORKAROUND :

One could keep using the various libraries available that support this properly (eg. Guava, Apache Commons, etc), but this defeats the purpose of having this functionality in the JDK.
