I read docs about suppressed exceptions. And of course I can run test. 
But still I wonder how it should behave, if there is more than one 
close-able resource, two of them raise exceptions, and there was no 
exception in main block (so no suppression).

Can anyone point me to relevant doc? Google is not very helpful.
