-------------------------------------------------------------------------
This test reproduces the issue (RawHttpServiceTest.java is attached). If you do
disable the line that provisions the amdatu log handler, no error appears. Same
when you disable the line that provisions the amdatu test bundle. Enabling both
however causes the error, so I'm still not sure if reading from config admin is
the actual problem although it seems related.

> As a consequence Shindig seems to fail proper startup. After investigation it
> seems that the issue is caused when a bundle retrieves the Felix http
> configuration entry before the Felix http bundle itself is started. Attached
> is the source of the bundle with which I can reproduce the issue, by
> providing this bundle to Pax Exam first, followed by the Felix http service
> bundle.
> The error appears when this code is executed in the start() method:
> m_configAdmin.getConfiguration("org.apache.felix.http", null); -> error is
> thrown
> However, without the location parameter the error does not appear:
> m_configAdmin.getConfiguration("org.apache.felix.http"); -> no error
> Also when reading other configuration entries, the error does not appear.
