Dimitris Andreadis closed JBAS-3870.
------------------------------------
Resolution: Done
The jbossmx javax.management.timer.Timer has been cloned into:
org.jboss.mx.timer.JBossTimer
The 2 JMX based schedulers:
org.jboss.varia.scheduler.ScheduleManager &
org.jboss.varia.scheduler.Scheduler
can utilitize the jboss timer (instead of the jdk5 javax.management.timer.Timer) if you
just instantiate it seperately:
<mbean code="org.jboss.mx.timer.JBossTimer"
name="jboss:service=Timer"/>
This is the default name there are looking for so they will use it automatically. You
could choose a different name, then configure the TimerName attribute on both schedulers.
Clone the JBossMX javax.management.timer.Timer implementation, to a
jboss package

Key: JBAS-3870
URL:
http://jira.jboss.com/jira/browse/JBAS-3870
Project: JBoss Application Server
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: JMX
Reporter: Dimitris Andreadis
Assigned To: Dimitris Andreadis
Fix For: JBossAS-5.0.0.CR1, JBossAS-4.2.0.CR1
There are indications that the jdk5 implementation of javax.management.timer.Timer uses
internally a single-threaded implementation for executing scheduled tasks, so scheduling
of multiple tasks is affected when moving from jdk1.4 and the jboss implementation of
Timer, to a jdk5 runtime.
The JBossMX Timer implementation in contrast uses a dynamically extensible thread pool to
execute scheduled tasks. Since we don't control the jdk5 implementation, a simple
solution is to clone the jboss timer into a new package, e.g.
org.jboss.javax.management.timer.Timer, for those that want to stick with the jboss
implementation.
