So you add a new object to the session store in each request and(!) keep the old objects referenced from a thread outside of the scope of the bridge?

someJavaObject should have been garbage collected, i.e. getParam1() should have returned null. If not, you have found the reason for the OOM.

>>then you've written a bug, I think.

Maybe! 
But the only code I have is 
$session = java_session();
$session->put("param1", someJavaObject);

On the other page I am doing
$someJavaObject = $session->get("param1");

That is all I have. 2 lines of code for the session in php and one line in
the second php.

BTW, $someJavaObject would be temporarily referenced by many threads on the
backend in the subsequent calls. Could that be the source of the problem?

>>It is not possible to keep the state w/o using java_session(), at least
not reliably.

As I mentioned earlier, I have apache http server and tomcat. Instead of
using java_session, I am using the session_id() within the apache server and
against that id I am storing a data structure in the backend.
So, on the first page I am doing
$sessionid=session_id();
$myBackendHodler.storeParam1($sessionid, someJavaObject);

On the second page I am doing
$sessionid=session_id();
$someJavaObject = $myBackendHodler.getParam1($sessionid);

Let me know if you think that is reliable.

I have gone through it but will go over it one more time.

Thanks

It is not possible to keep the state w/o using java_session(), at least not reliably.
