Re: Many many "java.lang.Object cannot be cast to
org.apache.activemq.command.Command"
Hi Benoit,
I just committed a change (r773986) that will output the object that
cannot be cast to a Command which should help track this down. This
change will be in tonight's snapshot if that is of help to you.

Re: Many many "java.lang.Object cannot be cast to
org.apache.activemq.command.Command"
Posted by Gary Tully <ga...@gmail.com>.
nightly snapshot (kits) are at
https://repository.apache.org/content/repositories/snapshots/org/apache/activemq/apache-activemq/5.3-SNAPSHOT/
The maven2 component dependencies are at the same repo root.
Reproducing with the latest snapshot will also ensure that stack
traces are up to date which will help with diagnosis.

Posted by Benoitx <be...@yahoo.com>.
Hi Gary,
Thanks for doing this.
Could you confirm where the overnight builds are? it seems that I only have
a snapshot from April 30 on the repo where I look (We build under m1...so
I'll have to copy it)
Thanks
Benoit.
