Description

When image files (Content-Type: image/gif, image/jpeg, image/jpg) are attached to emails and
Apache James 3.0 Beta4 serves as an MTA I am getting these exceptions on MimeBodyPart.getContent() calls below (while processing the mail within the attached
test.mailet.BodyPartExtractingMailet mailet). This is due to the fact that as of Apache James Beta4
it ships with Geronimo JavaMail implementation (geronimo-javamail_1.4_mail-1.6.jar) that is the cause
of this exception (with Apache James Beta3 Oracle JavaMail implementation (mail-1.4.4.jar) handled
this correctly without exceptions).

Precise steps to reproduce :

1. Deploy the attached test.mailet.BodyPartExtractingMailet to run within Apache James Beta4

a. package it as a jar and put it under JAMES/lib
b. add <mailet match="All" class="test.mailet.BodyPartExtractingMailet"/> to
JAMES/conf/mailetcontainer.conf
c. add log4j.logger.test.mailet.BodyPartExtractingMailet=DEBUG, CONS, FILE to
JAMES/conf/log4j.properties
d. (re-) start James, tailing -f either JAMES/log/mailetcontainer.log or JAMES/bin/wrapper.log

2. Using your favorite email client send an email to yourself (with Apache James processing
your email) containing attachments with MimeTypes image/jpeg, image/jpg and image/gif
(surprisingly enough image/png is handled without an exception). You can use attached
btnbg_over.jpg and up_15x15.gif.

3. Observe these exceptions in the log file

Note #1: removing geronimo-javamail_1.4_mail-1.6.jar from the classpath fixes the problem (ie, no
exceptions are thrown). However, you can't just comment the line out
wrapper.java.classpath.88=%REPO_DIR%/geronimo-javamail_1.4_mail-1.6.jar
in JAMES/conf/wrapper.conf as all jars after this line will be lost (as they are expected to be in order); hence just set the JavaMail (mail-1.4.4.jar) which was already set up earlier (as Classpath argument 10) ... as also jar argument 88
wrapper.java.classpath.88=%REPO_DIR%/mail-1.4.4.jar
).

Note #2: This issue might be documented in https://issues.apache.org/jira/browse/GERONIMO-5415
and was supposedly fixed in geronimo-javamail_1.4_mail-1.8.1.jar (however Apache James Beta4 is using an older geronimo-javamail_1.4_mail-1.6.jar). I don't know whether Apache James really needs
geronimo-javamail implementation as Oracle's JavaMail (ie. mail-1.4.4.jar) seems to handle this
correctly.
