Using pax-logging-service bundle hang JBoss
Hello,
I have an osgi web application using equinox servlet briges in order to be packaged as a legacy WAR file and deployable in non osgi application server, like jetty, tomcat, and jboss (older version than 7)
I am using pax-logging service bundle inside my application. After deploying my application, the whole JBoss container stop reponding, because StackOverflow occurs each time someone logs someting inside the container.
Internally, pax-logging use log4j and I noticed stackoverflow occured when something was logged using default root logger (on stdout).
After configuring pax-logging ( -Dorg.ops4j.pax.logging.DefaultServiceLog.level=ERROR) to prevent something to be logged using this logger, it remove the Stackoverflow issue, but JBoss does not output anything anymore. So it seems that all JBoss logs go through pax-logging, even for other applications than mine.
I am quite surprised, because I thought JBoss 6 did not use log4j anymore, so I do not understand, why pax-logging is conflicting with JBoss
Is there any way to isolate pax from my application to conflict with some JBoss logging layer ?
Also just for information, in order to check I tried to deploy pax-logging service bundle directly in JBossAS 7, and there is exactly the same issue, JBoss hang because of same stackoverflow.
And the stack trace of StackOverflow is:
