[jira] [Commented] (FELIX-5563) Adding extension bundles causes
wildfy/tomcat server to fail
[ https://issues.apache.org/jira/browse/FELIX-5563?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16265142#comment-16265142 ]
Frank Blom commented on FELIX-5563:
-----------------------------------
After seeing the update of the framework 5.6.10 we again decided to try getting extension bundles to work again, focusing more on the tomcat server.
Our OSGi container runs inside our tomcat server. When the OSGi container is started with an extension bundle deployed, startup fails with following exception:

When I debug trough the process it seems like the extension bundle is picked up and handled by the DefaultClassLoaderExtender in the ExtensionManager.
The DefaultClassLoaderExtender recognizes that the Tomcat ParallelWebappClassLoader is a subclass of UrlClassLoader.
However, during starting/resolving the bundle, the above validation check fails.
I'm assuming the Felix framework library can be upgraded without the need to upgrade other Felix libraries. The versions that are used:
"org.apache.felix:org.apache.felix.configadmin": "1.2.8",
"org.apache.felix:org.apache.felix.dependencymanager": "3.1.0",
"org.apache.felix:org.apache.felix.fileinstall": "3.2.4",
"org.apache.felix:org.apache.felix.framework": "5.6.10",
"org.apache.felix:org.apache.felix.http.api": "2.2.2",
"org.apache.felix:org.apache.felix.http.bridge": "2.2.2",
"org.apache.felix:org.apache.felix.http.proxy": "2.2.0",
"org.apache.felix:org.apache.felix.main": "5.6.10",
The extension bundle does start correctly in a standalone Felix 5.6.10 framework. There it works fine and the bundle behaves as expected.
