      Description



      Name: aaR10208 Date: 04/30/2003


      Filed By : J2SE-SQA [###@###.###
      JDK : JDK1.4.2-b21
      Testbase : RegTest-cte
      Platform[s] : Solaris 9 (x86) (CDE), SMP, 4 CPUs (unable to reproduce on single-CPU box).
      switch/Mode : -server
      Falling test[s]: CTE_REGTEST/Generic/4820217/StreamsSurviveDestroy.java

      The test performs 4 steps: test(), testCloseBeforeDestroy(), testCloseAfterDestroy(), testInterrupt()
      and there is an intermittent failure in the testCloseAfterDestroy().

      Most probably the failure is caused by the racing in the test (see also output logs below):
      the stream copiers receive EOF from the process' output and error streams and stop working before
      the test calls Process.destroy(), so the test fails.

      Please note, that the failure is intermittent, and I was not able to reproduce it on my single-cpu
      solx86 box after 10 runs.

      #TESTBASE=/net/linux-15/export/home/java/regtest/cte
      TEST=StreamsSurviveDestroy
      cp ${TESTBASE}/CTE_REGTEST/Generic/4820217/$TEST.java .
      ${JDK}/bin/javac ${TEST}.java
