Frank Blom commented on FELIX-5563:
-----------------------------------
Yes, it looks like this is happening. Fileinstall does check for
fragmentbundles but not for extension bundles. When fileinstall tries to start
the extension bundle it passes the bundle to the framework to start it, I can
see that the framework then detects it is a extension bundle and does not start
it.
We have made an empty webapp with only standard bundles including fileinstall
and adding a extension bundle, but we haven't been able to reproduce the
problem.
Still working on it.
