I did find the NoSessionCreationFilter, however its Javadoc is not reassuring
at all:
* <li>
* However, if the {@code Subject} already has an associated session before this
filter is invoked, either because it
* was created in another part of the application, or a filter higher in the
chain created one, this filter has no
* effect.
* </li>
This is not what I want: even if something somewhere created a Session for some
obscure / bogus reason, I don’t want Shiro using it to cache subjects. Is there
a bombproof way of achieving this?
Thanks!

Subject: Re: ThreadContext not cleaned up after REST request
I made some progress: the problem disappears if the client doesn’t send the
JSessionID cookie… so this is a session management problem (the two requests w/
different credentials came from the same session).
I had been hoping that this would be enough to disable sessions altogether?
securityManager.subjectDAO.sessionStorageEvaluator.sessionStorageEnabled = false

Subject: Re: ThreadContext not cleaned up after REST request
Take a look at
https://shiro.apache.org/subject.html#thread-association<https://urldefense.proofpoint.com/v2/url?u=https-3A__shiro.apache.org_subject.html-23thread-2Dassociation&d=DwMFaQ&c=ObqWq9831a7badpzAhIKIA&r=nQOltkjOzdXqkPdbNY4_HrRBjeSbKdDUhyndw0GHR7M&m=d2ZwgM0QaCqU3iMd8ajna0ixN8ytuv8QuvA8VG5Q3yY&s=ZUxl3fOiUdbjYZbLEmluV2aCpJWrkE0h_GE5P4wMq5s&e=>
Async Servlets are processed outside the context of a thread (different thread
pool). Typically you need to configure the binding/unbinding of the subject to
those threads using a different mechanism. If you put together a simple
reproduction example we can probably point you in the right direction (possibly
turning it into an official example)

Hi all,
We have a stateless JAX-RS application that uses Shiro. Once a user has
authenticated and its Subject has been put in the ThreadContext, shiro will
return that Subject for all subsequent requests processed by the same Tomcat
thread.
Going through the logs this seems to happen because
AbstractShiroFilter#doFilterInternal calls createSubject(...) before calling
subject.execute(...)
createSubject somehow binds the Subject to the session, however there is no
corresponding unbind call, as confirmed by the logs (see below) "Bound value of
type..." and "Removed value of type..." entries.
I have been pounding my head against the wall with this, any help would be
greatly appreciated!
Thanks,<raw></raw>

The logs for the first request to come in looks like this: our Realm is invoked
to authenticate the request, but there is no "Removed value of type..."
anywhere in the logs so the authenticated Subject remains in the ThreadContext:
