The following methods will all throw the
IllegalStateException
if the session object is invalid:
SessionData.putValue
SessionData.getValue
SessionData.removeValue
SessionData.isNew
SessionData.getMaxInactiveInterval
The following is an
IllegalStateException
:

Two threads within the JVM™ both gain access to the session object. One thread invalidates the session and then the other thread attempts to use the session object
The following steps occur within the same request:
HttpSession mySession = request.getSession();
The
mySession.invalidate()
method is called.
One of the following methods is called on the session object:
mySession.putValue(myString, "is the session invalid");
mySession.getValue(myString);
mySession.removeValue(myString);
mySession.isNew();
Any other attempted operation on the session object.
Check the servlet or JavaServer™ Pages (JSP) that threw the exception to determine if the scenario described above applies to your situation. If not, continue to the next section.
Two threads within the JVM both gain access to the session object. One thread invalidates the session and then the other thread attempts to use the session object.
1. Application code in Thread-1 gains access to the session object by calling:
HttpSession mySession = request.getSession();
2. Application code in Thread-1 gains access to the session object by calling:
HttpSession mySession = request.getSession();
3. Application code in Thread-2 gains access to the same session object by calling:
HttpSession mySession = request.getSession();
4. Thread-2 invalidates the session object.
5. Thread-1 attempts to use the session object by calling one of the following methods:
mySession.putValue(myString, "is the session invalid");
mySession.getValue(myString);
mySession.removeValue(myString);
mySession.isNew();
Any other attempted operation on the session object.
