Hi, Sherman.I'm glad to see this coming in. As you said, long overdue. I'm curious. What are the plans are to encourage migration from the JDK private and unsupported sun.misc.BASE64{En,DE}coder classes? Compile-time warning? Documentation? Something else?
On that point, sun.misc.BASE64{En,DE}coder may present a fine opportunity to use the @Deprecated annotation...

Thanks, iris -----Original Message----- From: Xueming Shen Sent: Wednesday, October 10, 2012 10:55 AM To: core-libs-dev Subject: Review/comment needed for the new public java.util.Base64 class A standard/public API for Base64 encoding and decoding has been long overdue. JDK8 has a JEP [1] for this particular request. Here is the draft proposal to add a public Base64 utility class for JDK8. http://cr.openjdk.java.net/~sherman/4235519/webrev This class basically provides 4 variants of Base64 encoding scheme, (1) the default RFC 4648, which uses standard mapping, no line breaks, (2) the URL-safe RFE 4648, no line breaks, use "-" and "_" to replace "+" and "/" for the mapping (3) the default MIME style, as in RFC 2045 (and its earlier versions), which uses "standard" base64 mapping, a 76 characters per line limit and uses crlf pair \r\n for line break. (4) an extend-able MIME base64, with the char-per-line and the line separator(s) specified by developer. The encoder/decoder now provides encoding and decoding for byte[], String, ByteBuffer and a pair of "EncoderInputStream" and "DecoderOutputStrream", which we believe/hope should satisfy most of the common use cases. Additional method(s) can be added if strongly desired. We tried couple slightly different styles of design for such this "simple" utility class [2]. We kinda concluded that the version proposed probably provides the best balance among readability, usability and extensibility. Please help review and comment on the API and implementation. Thanks! -Sherman [1] http://openjdk.java.net/jeps/135 [2] http://cr.openjdk.java.net/~sherman/base64/
