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]).
[1]
java.lang.reflect.InaccessibleObjectException: Unable to make field private final byte[]
java.lang.String.value accessible: module java.base does not "opens java.lang"
to unnamed module @3d5c822d

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

Hello Sean,
Which James server flavour are you using? (distributed, spring, guice-jpa,
etc... )
Which version of James are you running>
ClosedChannelException in IMAP are unrelated to email delivery and fully

Hello,
I have a system that uses Apache James, and it has been functioning well until

It would appear that messages are being sent, but not delivered. I get no
