Hi

I have app which were running in cluster and was configured in that way. Now i need run this app on one host. I have problem when my app calls function request.getSession(). It returns null and i got NullPointerException in code like below.

request.getSession().getAttribute(...);
request.getSession().setAttribute(..., ....);

Something is strange, because i see this behavoiur only if I set up log4j with ERROR for com.myapp (turn off debugging in production env). When I turn debug on, everything is OK.

Version: 4.0.3SP1(build: CVSTag=JBoss_4_0_3_SP1 date=200510231054)
JVM Version: 1.5.0-b64 (Sun Microsystems Inc.)
OS: Linux 2.6.11.4-20a-smp (i386)

Any suggestions? It's problem with session replication?
