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. | 2008-06-12 15:34:32,864 FATAL [org.jboss.serial.persister.RegularObjectPersister] error |
