      Regression test java/awt/Frame/DisposeStressTest/DisposeStressTest.html test fails very intermittently with JDK1.5.0.
      The following output appears in the jtr:

      The test fails very rarely but you can try to reproduce the failure using the script provided below.
      I looked over KeyboardFocusManager.java and found the following:

      KeyboardFocusManager.retargetFocusLost(FocusEvent fe) consists basically of 4 branches of execution.
      The first three perform checking if currenFocusOwner is null, but the last branch does not contain such checking
      and passes currenFocusOwner directly to the FocusEvent constructor causing IllegalArgumentException in
      the EventObject constructor. Please see the stack trace above for exact line numbers.

      I'm filing this bug in hope that although the failure is hardly reproducible the developers may agree
      that it worth to add "if (currentFocusOwner == null)" into the last branch of execution.

      How to reproduce:
      =================
      Run the following script (you may need to change its variables)

      --- script start ---
      #!/bin/sh
      RESULT_DIR=`pwd`
      WORK_DIR=$RESULT_DIR/workDir/test
      REPORT_DIR=$RESULT_DIR/reportDir

      JAVA_HOME="/net/linux-15/export/home/java/jdk1.5.0/x86"
      TEST_BASE_PATH="/net/linux-15/export/home/java/regtest.tiger/test"
      TESTVMOPTS="-client"
      CLASSPATH="$JT_HOME/classes:$JT_HOME/lib/javatest.jar:$JT_HOME/lib/jtreg.jar"

      TEST="java/awt/Frame/DisposeStressTest/DisposeStressTest.html"

      mkdir -p $WORK_DIR/scratch 2>&1
      mkdir -p $WORK_DIR/jtData 2>&1
      mkdir -p $REPORT_DIR 2>&1

      #rm $WORK_DIR/jtData/ResultCache.jtw 2>&1

      cd $WORK_DIR/scratch

      $JAVA_HOME/bin/java -server -cp $CLASSPATH -DenvVars=TESTJAVAHOME=$JAVA_HOME,TESTVMOPTS=$TESTVMOPTS,DISPLAY=:0,HOME=$HOME/.regtest,PATH=/bin:/usr/bin,CPAPPEND=$JT_HOME/jemmy/jemmy.jar,TZ=,LC_ALL=en_US,LC_CTYPE=en_US,LANG=en_US,LPDEST= -DDISPLAY=:0 -DlocalHost="linux-18" -Dprogram=jtreg com.sun.javatest.regtest.Main -a -v default -batch -params -w "$WORK_DIR" -r "$REPORT_DIR" -t "$TEST_BASE_PATH" "$TEST_BASE_PATH/$TEST"
