h2. Problem
When an IMAP message is expunged between fetch time and the on-completion
commit callback, {code}IMAPMessage.setFlag(){code} throws
{code}javax.mail.MessageRemovedException{code} whose {code}getMessage(){code}
returns {code}null{code}. This surfaces in the Camel error log as:
{noformat}
Error occurred during committing mail message:
com.sun.mail.imap.IMAPMessage@542a494d.
Exchange[B5882D23412732A-0000000000000013]. Caused by:
[javax.mail.MessageRemovedException - null]
{noformat}

h2. Fix
Catch {code}MessageRemovedException{code} before the generic
{code}MessagingException{code} handler in
{code}MailConsumer.processCommit(){code} and wrap it with an explicit
description. Expected log after fix:
{noformat}
Caused by: [javax.mail.MessagingException - Message already removed/expunged on
server (no flag update possible)]
{noformat}
h2. PR
PR opened against apache/camel main with fix + 2 unit tests. Developed with AI
assistance (Claude Code) per Apache Camel contributing guidelines.
