This is what a sample crash message looks like before applying patch:
Kernel pid terminated (application_controller)
({application_start_failure,cmp,{{bad_return_value,
{doc_root_not_exists,[46,47,119,119,119]}},{cmp_app,start,[normal,[]]}}})

It was possible to insert {Mod::atom(),Vsn::term()} instead of
Mod::atom() in the modules list in a .app file. This was not visible
in the documentation of .app files, but it was visible in the
documentation of application:load/[1,2] (where the .app file term can
be used directly as first argument).
The Vsn part was never used, so this possibility has now been removed.

When a node is shutting down, application_controller will do
exit(Pid,shutdown) on all application masters, and wait for
{'EXIT',Pid,_}. If, for some reason, the application master does not
terminate then application_controller will hang forever waiting for
this 'EXIT' message.
To overcome this problem, a configurable timer is added to kernel -
the enviroment variable 'shutdown_timeout'. If this variable is set to
a positive integer T, application_controller will do exit(Pid,kill)
after T milli seconds if no 'EXIT' message is received.
