6:28 a.m.
Hello,
I am developing an application in the following environment
* Framework: Seam 1.2.GA (problem not related to Seam)
* JBoss: 4.0.5.GA + EJB3
* VM: jdk 1.5.0_09-b03
* DB: postgres
* O/S: Linux Debian
I encountered an exception (see stacktrace) which loops infinitely and forces me to kill
the server.
I suspect that the exception occurs at passivation of one of my SFSB. Somehow the
serialization process enters in a recursive loop while writing a HashMap, but I am not
sure weather the root cause is the IOException or the StackOverflow (see stacktrace).
In the exception there is no trace of my application classes.
I enabled DEBUG level logging for org.jboss.serial and
org.jboss.ejb3.cache.simple.StatefulSessionFilePersistenceManager classes, reduced
drastically the passivation timeout to 10secs and tried to execute the same actions that I
had done when I first noticed the bug on my application, but I didn't yet manage to
reproduce it.
In the DEBUG log I noticed that the serialization of the most complex Beans takes very
long time to serialize (~2secs). My Beans were actually not very well written in
"Serialization-terms" (no serialVersionUID, no declaration of transient fields
and no implementation of @PrePassivate and @PostActivate callback methods), since I
don't really need passivation in my application. I will probably disable it, but I
still would like to understand this bug.
Also, I didn't find very much about similar problems on forums.
Can anyone help?
Here is the stacktrace. In the original "infinite" stacktrace, many parts were
repeated, so I replaced them by comments.
