      Description



      Name: vsR10238 Date: 09/02/2003


      Filed By : J2SE-SQA [###@###.###
      JDK : JDK1.5.0-b17
      Testbase : Regression-test
      Platform[s] : Solaris 10 (x86, sparc)
      Falling test[s]:
               javax/sound/sampled/Lines/SDLwrite.java
      javax/sound/sampled/Lines/SourceDataLineDefaultBufferSizeCrash.java

      2 tests from the regression test suite for JDK1.5.0 fail with JDK1.5.0 (tested with b17, b16),
      JDK1.4.2 (tested with b28) on computers without sound or if sound services are unavailable due
      to other restrictions.

      The tests fail because com.sun.media.sound.SimpleInputDevice.implOpen() called from Mixer.open()
      throws NullPointerException.

      According to the J2SE 1.5.0 API specification Line.open() inherited by the Mixer interface does not throw
      NullPointerException.

      javax/sound/sampled/Lines/SourceDataLineDefaultBufferSizeCrash.java is a new test introduced in
      the regression test suite for JDK1.5.0-b17.

      Test source location:
      =====================
      /java/re/jdk/1.5.0/promoted/latest/ws/j2se/test/javax/sound/sampled/Lines/SDLwrite.java
      /java/re/jdk/1.5.0/promoted/latest/ws/j2se/test/javax/sound/sampled/Lines/SourceDataLineDefaultBufferSizeCrash.java

      jtr file location:
      ==================

      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
      JT_HOME="/net/linux-15/export/home/java/jct"
      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="javax/sound/sampled/Lines/SDLwrite.java"

      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"

      --- script end ---
