Cannot start hybris on Ubuntu Linux 14.04

Hello,

we've installed hybris on Ubuntu Linux and it fails to start, no exception is shown in the console and in the log files. It simply stops loading after showing the line:

 2015-08-25 15:01:28,195 [INFO ][localhost-startStop-1][de.hybris.platform.regioncache.DefaultCacheController] Registered Listener RegionCacheAdapter(1812653376) - <<master>> on cache controller. Currently registered 1

What could be the problem? Is it possible to start hybris in verbose mode in order to see what the problem is ? How can we avoid the problem? The complete start log is attached (see attachment).

Many thanks in advance!
