Description




Filed By       : J2SE-SQA [j2se-tck-  xxxxx@xxxxx  ]
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:
==================
/net/jtgb4u4c.sfbay/export/sail15/results.2/tiger/b17/regtest/x86/sol10_x86_gnome_linux-18/workDir/test/javax/sound/sampled/Lines/SDLwrite.jtr

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 ---
