For what it's worth months ago my james instance broke when I upgraded
to java 17, I posted about it here but no one could reproduce so I left
it on 11, months later I upgraded to 17 again and everything was working
fine so I thought nothing more about it. Recently, however, it stopped
sending mail/showing mail in thunderbird for whatever reason, it had
been working on Java 17 but on the 26th of this month it decided to
stop. Digging through the logs I found these exact same stack traces, I
added the following to JAVA_OPTS which fixes the stack traces and
immediately caused a flood of email that had been queued for sending to
send and my inboxes to flood with all the mail I had received since
things broke. It looks like james was still queuing mail for send and
receiving mail during this time but it never actually finished those
processes until I fixed the reflection issues. Hopefully someone finds
this info useful.
JAVA_OPTS=--add-opens=java.base/java.lang=ALL-UNNAMED\
--add-opens=java.base/java.math=ALL-UNNAMED\
--add-opens=java.base/java.util=ALL-UNNAMED\

Does this affect Apache James or my client code? Does Apache James need to use
java 1.8, or does my code have to use 1.8?

Hello,
Yes it helps.
In java versions above java 11, java is more restrictive about reflection (as
shown in [1] ) and here the JMS mailqueue fails at initializing stuff to read
emails in the queue (shown in [2]). The FST serializer makes heavy usage of
reflection and needs to be allowed to do so (as shown in [3]).

My theory: you ingested a mail with a serialized attribute and now due
to restrictions in the way you run java 11 you fail at deserializing
it... The mail is well received in SMTP, well enqueued but can't be
dequeued.
My suggestion: relax those checks.
CF add this to your java argline
--add-opens java.base/java.lang=ALL-UNNAMED --add-opens
java.base/java.math=ALL-UNNAMED --add-opens
java.base/java.net=ALL-UNNAMED --add-opens
java.base/java.text=ALL-UNNAMED --add-opens
java.base/java.util.concurrent.atomic=ALL-UNNAMED
--add-opens java.base/java.util.concurrent=ALL-UNNAMED
--add-opens java.base/java.util=ALL-UNNAMED
FYI dropping fully FST is a long lasting desire I have CF
