I've seen this test fail on at least two occasions on linux-x86 with jdk7-b145. The tests are run with -agentvm and so are running tests sequentially in the same VM (to avoid starting a VM per test). It's possible that there are threads from previous tests or longer GC times due to garabge from previous tests that may be an influence here. #Test Results (version 2) #Tue Jun 21 12:54:22 IST 2011 #checksum:38b2177ceef6127e #-----testdescription----- $file=/export/Users/ab23780/ws/jdk8/tl/jdk/test/java/util/concurrent/Executors/AutoShutdown.java $root=/export/Users/ab23780/ws/jdk8/tl/jdk/test author=Martin Buchholz keywords=bug6399443 othervm run=USER_SPECIFIED main/othervm AutoShutdown\n source=AutoShutdown.java title=Check for auto-shutdown and gc of singleThreadExecutors #-----environment----- #-----testresult----- description=file:/export/Users/ab23780/ws/jdk8/tl/jdk/test/java/util/concurrent/Executors/AutoShutdown.java elapsed=473 0:00:00.473 end=Tue Jun 21 12:54:22 IST 2011 environment=regtest execStatus=Failed.
