[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=16287736#comment-16287736 ]
Frank Blom commented on FELIX-5563:
-----------------------------------
So far we have tried a few different scenarios.
When the extension bundle is added through the felix shell by executing the install file:path\to\bundle.jar command, the extension bundle resolves and the application works as expected.
When the extension bundle is copied at runtime to the directory watched by apache.felix.fileinstall, the exception java.lang.IllegalStateException: Invalid BundleContext is thrown.
This error is thrown when the framework is restarting the apache.felix.http.bridge bundle. The bundlecontext that is invalid is the apache.felix.framework bundle.
When looking into the osgi container on Tomcat the bundle states are as expected, the extension bundle is resolved and the rest is active, so it looks fine.
Still the application is not working.
When using a clean standalone application with the standard bundles, adding the extension bundle is no problem.
The next step is to test in a clean webapp.
