Hi all,

Please review patch:

Problem:
if java doesn't crash in 'generate_replay' function due to some reasons, 
e.g. incompatible vm options like '-XX:CICompilerCount=1' (fixed by 
8038393) or problems w/ ulimit (fixed by 8032662), 'core_locations' 
variable will be an empty string, test will try to copy root directory 
to current directory, as a result jtreg will fail to clean up the directory

Fix:
fail tests w/ message about an absence of core file location, if 
'core_locations' variable is empty

jbs: https://bugs.openjdk.java.net/browse/JDK-8032498
testing:
  - failing tests in jprt
  - locally verified, that tests w/o fixes for 8038393, 8032662 fail as 
expected
