REGRESSION: IAE for supported line in AudioSystem.getLine()

Name: vtR10009 Date: 10/06/2003


AudioSystem.getLine(Line.info) method should not throw IllegalArgumentException
for lines that are supported by Java Sound framework.
This bug causes failure of JCK test:
  api/javax_sound/sampled/LineListener/index.html#LineListener

Note the test is passed by mantis (jdk1.4.2). So this is regression.
To reproduce the bug run the following test with JDK build 1.5-beta-b22:
------------------------------- test.java --------------------------------
import javax.sound.sampled.*;
import javax.sound.midi.*;

public class test {

    static boolean isSoundAccessDenied = false;
    static {
        SecurityManager securityManager = System.getSecurityManager();
        if (securityManager != null) {
            try {
                securityManager.checkPermission(new AudioPermission("*"));
            } catch (SecurityException e) {
                isSoundAccessDenied = true;
            }
        }
    }

    static final int STATUS_PASSED = 0;
    static final int STATUS_FAILED = 2;
    static final int STATUS_TEMP = 95;
    static java.io.PrintStream log = System.err;
    
    public static void main(String argv[]) { int testExitStatus = run(argv,
    System.out) + STATUS_TEMP; System.exit(testExitStatus); }

    public static int run(String argv[], java.io.PrintStream out) { String
        testCaseID = "LineListener2001";

        log.println("===== " + testCaseID + " =====");
    
        boolean failed = false;
        Line l = null;
    

    
        // get the default SourceDataLine
    
        DataLine.Info s_info = new DataLine.Info(SourceDataLine.class, null);
        Line.Info infos[] = AudioSystem.getSourceLineInfo( s_info );
    
        if( infos.length < 1 ) {
            log.println("Line.Info array == 0");
            return STATUS_PASSED;
        }
        try {
            l = AudioSystem.getLine(infos[0]);
        } catch(SecurityException lue) {
            log.println("SecurityException");
            return STATUS_PASSED;
        } catch (LineUnavailableException e1) {
            log.println("LUE");
            return STATUS_PASSED;
        } catch (IllegalArgumentException iae) {
            log.println("IllegalArgumentException should not be thrown "
                     + "for supported line");
            iae.printStackTrace(log);
            return STATUS_FAILED;
        }
        out.println("Passed.");
        return STATUS_PASSED;
    }
    
} // end of test class
