Filed By : J2SE-SQA [j2se-tck- xxxxx@xxxxx ]
JDK : JDK1.5.0-b22
(the test fails with previous JDK builds because of the bug 4616517)
JCK : JCK1.5-runtime (b05)
Platform[s] : customer Linux 9.0 (GNOME1), Solaris 8 (sparc) (CDE), Suse Linux 8.2 (GNOME2)
(not reproducible on Windows)
switch/Mode : default
JCK test owner : http://javaweb.eng/jck/usr/owners.jto
Falling test[s]: api/javax_sound/midi/Receiver/index.html#Receiver [Receiver001, Receiver003, Receiver004]
JCK1.5-runtime api/javax_sound/midi/Receiver/index.html#Receiver test fails with JDK1.5.0-b22.
Java TM 2 Platform Std. Ed. v1.5.0 API Specification reads about MidiSystem.getReceiver() method:
...
public static Receiver getReceiver()
throws MidiUnavailableException
Obtains a MIDI receiver from an external MIDI port or other default source.
If the system property javax.sound.midi.Receiver is defined or it is defined in the file
"sound.properties", it is used to identify the device that provides the default receiver.
For details, refer to the class description.
Returns:
the default MIDI receiver
Throws:
MidiUnavailableException - if the default receiver is not available due to resource restrictions
...
However, this method unexpectedly throws java.lang.IllegalArgumentException if default receiver
is not specified. It happens both on systems which can play midi and on systems which can not.
The following test example demonstrates the bug:
--------- test.java ---------
import javax.sound.midi.*;
public class test {
public static void main(String[] args) {
System.out.println("Default is " + System.getProperty("javax.sound.midi.Receiver"));
try {
Receiver r = MidiSystem.getReceiver();
System.out.println(r);
}
catch (javax.sound.midi.MidiUnavailableException e) {System.out.println ("OK");}
}
}

Please, note that javax.sound.midi.Receiver system property is not defined in the
<JRE>/lib/sound.properties file by default.
Also please note that JDK implementation and MidiSystem class API Specification were changed in
JDK1.5.0-b22 and this test example does not throw any exception with JDK1.5.0-b21.
