Jason Greene reopened JBAS-8652:
--------------------------------



Due to feedback from the community, I have split the AS7 and AS6 projects and reopened all unscheduled AS6 issues that are a year or less old. This will make it easier community members to find and work on them.

Future releases beyond 6.1 can be done provided a community member steps up to coordinate them.

> On startup of JBoss 5.1.0-GA  sometimes (seen it several times) it comes to a Thread deadlock between the main thread and an other Thread.
> We use XA datasources and we have configured in the file conf/jbossts-properties.xml the Arjuna Transaction Manager Recovery Module.
>     <properties depends="arjuna" name="jta">
>         <property name="com.arjuna.ats.jta.recovery.XAResourceRecoveryJDBC" value="com.arjuna.ats.internal.jbossatx.jta.AppServerJDBCXARecovery;jndiname=nxcore/resource/DS"/>
> This RecoveryModule is triggered during startup in a Thread which causes together with the "main" Thread a deadlock
> in the method toClass() of the class org.jboss.aop.asintegration.jboss5.ToClassInvoker.
> 1.) The "main" Thread has already locked the org.jboss.classloader.spi.base.BaseClassLoader and waits to lock the "tmplock" Object in class ToClassInvoker.
> 2.) The other Thread ("Thread-20") has already locked the "tmplock" Object and waits to lock the BaseClassLoader for the call
> of the synchronized method loadClass() (myloader.loadClass()).
> Source can be seen here:
> http://grepcode.com/file/repository.jboss.com/maven2/org.jboss.aop/jboss-aop-asintegration-mc/2.1.1.GA/org/jboss/aop/asintegration/jboss5/ToClassInvoker.java#ToClassInvoker
> IMHO a locking of the BaseClassLoader "synchronized (myloader)" before the locking of the "tmplock" Object should prevent this deadlock situation.
