[jira] [Commented] (AMQ-3633) [OSGi] activemq-web-console:
exception after restart container
[ https://issues.apache.org/jira/browse/AMQ-3633?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15176227#comment-15176227 ]
David Jencks commented on AMQ-3633:
-----------------------------------
Based on some experiments I'm doing with the activemq web console installed as an esa in WAS Liberty (which runs on equinox) I very much doubt this is a problem that can be solved in activemq. The problem appears to be that the jdk code is attempting to use a bundle classloader to load it's own classes. I find that adding the relevant package to the boot delegation allows this to work. For me this is done by adding the framework property
org.osgi.framework.bootdelegation=javax.management.remote.rmi
You might need other boot delegation packages as well, so this particular setting might not be appropriate everywhere.
Equinox can also have implicit boot delegation, although this seems to have a fairly large performance penalty. I'm not sure which versions of equinox have this on or off by default; this might explain the difference in behavior between equinox 3.6 and 3.8. To turn it on (unless otherwise disabled by launch code):
osgi.context.bootdelegation=true
