FULL PRODUCT VERSION :
java version "1.4.2_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
Java HotSpot(TM) Client VM (build 1.4.2_03-b02, mixed mode)


A DESCRIPTION OF THE PROBLEM :
The JDK (and therefore by extension JavaMail) does not seem to support any mail encoded with an HZ-GB-2312 encoding. The Macintosh Mail.App 5 produces mail with this encoding when sending Chinese characters. HZ-GB-2312 is defined by RFC 1842, which has existed since 1995, so it seems as though Java should support it natively.

I submitted this report to the JavaMail group and was told to resubmit to the JDK group.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a mail whose MIME parts are encoded in the HZ-GB-2312 charset. 2. Create a javax.mail.internet.MimeMessage object with its input stream containing the mail from step 1. 3. Call getContent() on the object from step 2, to get a MimeMultipart. 4. Call getContent() on the MimeMultipart object.



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I should get the contents of the mail as a Unicode Java String.
ACTUAL -
An UnsupportedEncodingException is thrown.


REPRODUCIBILITY :
This bug can be reproduced always.
