Add clarification of logging.file (fixes gh-1416)
Merge branch '1.1.x'
Add secure sample with JDBC and data.sql

We can't easily solve the problem by not allowing Spring Security to
eagerly instantiate everything, but we can be defensive about data.sql
and make sure it is executed even if the listener isn't yet registered.

Fixes gh-1386

Bump version in new sample
Log exceptions in ErrorPageFilter

For some reason I thought that the DispatcherServlet default handler
would log all exceptions, so if we did it in the ErrorPageFilter it
would lead to duplicates. That appears not to be the case.

Fixes gh-1427
Merge branch '1.1.x'
Add a little more context to ErrorPageFilter log

Add the servlet and context path along with the exception message to
the error logged in ErrorPageFilter.
