DataHandler doesnt use proper encoding after publishing a Webservice

[LanceAndersen]

Previously tracked via: https://bugs.openjdk.java.net/browse/JDK-7029376

FULL PRODUCT VERSION :
java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Windows 2008 64Bit, Windows XP 64-Bit

A DESCRIPTION OF THE PROBLEM :
The DataHandler doesnt pay attention to the character-set after you publish a webservice via Endpoint.publish(..., ...).

The encoding is regarded when you dont publish a webservice.

I used a MimeBodyPart for testing but i could track the problem to the JDK-classes.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Please use the attached source-code. In order to compile you need mail.jar but the bug seems not to be related to this package.
run the code and take a look at system.out.
The umlauts are encoded in the same way in both lines despite different parameters for the encodign (utf-8 and iso-8859-1).
Uncomment the line with Endpoint.publish(..) and the line are encoded differently as they should be.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The encoding should be regarded. The umlauts should be encoded like:

=F6=E4=FCtest231
=C3=B6=C3=A4=C3=BCtest231
ACTUAL -
With the probided example the output looks like this:

=C3=B6=C3=A4=C3=BCtest231
=C3=B6=C3=A4=C3=BCtest231

or

=F6=E4=FCtest231
=F6=E4=FCtest231

depending on the file.encoding environment variable.

REPRODUCIBILITY :
This bug can be reproduced always.
