Hello Sling team,
last days I started playing around with the latest Sling trunk. I
noticed that after the big changes that happened in the last weeks, the
sample application does not work anymore.
After some debugging I noticed, that the script resolving looks under
different paths than the current sample app stores its scripts. So I
corrected the paths according to the locations the script resolver is
using. In my instance the scripts are now available at
/apps/sling/SampleContent, /apps/sling/SamplePage and
/apps/org/apache/sling/sample.
Now the script resolver is able to find the right script, but there is
still no output returned for my request. The problem is probably that
during installation of the sample app the OCM mapping is not able to
find the SamplePage and SampleContent classes in the bundle, as
indicated by the exceptions I found in the error log (see stack trace
below).

This exception probably leads to the problem that the script can not be
compiled as indicated by the next exception that occured when I try to
access the page at
