With Felix 1.4.1 we can start Felix within Tomcat 6 without any problems. Thank you for the fix.

[jira] Resolved: (FELIX-842) Linkage-Error when embedding Felix
inside Tomcat 6
Posted by "Karl Pauls (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/FELIX-842?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Karl Pauls resolved FELIX-842.
------------------------------
Resolution: Fixed
The WebAppClassloader is creating urls during a classload while we are creating url handlers which gets us into a recursive attempt to create a handler resulting in the error. I addressed this in trunk by creating a couple of known built-in handlers up front (i.e., http, https, ftp, jar, file) which we can fallback to in case we get a Linkage-Error while trying to create the handler. Furthermore, a couple of classes are forced to be loaded eagerly.
Thanks again for reporting. This will make it into the upcoming 1.4.1 release. Please close this issue if it works for you.

Karl Pauls commented on FELIX-842:
----------------------------------
This looks bad. The issue is that the tomcat WebappClassLoader is creating URL's while doing a classload. Now, what happens is that when we set our URLHandlers it is asked to get a handler for a URL needed for a classload. Getting the handler involves loading classes which triggers another classload via the WebappClassLoader and there we go...
As mentioned, one solution is to diable URLHandlers for now if you run into this. Another could be to do what I will do internally to resolve this issue externally namely, preload all classes that we need inside a handlers lookup. I will add a comment with all the classes you need to preload soon.
Thanks for reporting!
