Linux: sun.tools.debug.RemoteDebugger constructor throws java.lang.InternalError

Name: asR10013 Date: 05/18/2000


    The sample code below shows incorrect behavior of RemoteDebugger constructor.
    Note that command reported by debugger is executed without errors when
started manually from command prompt.
    Also note that problem exists only in classic JVM. Under Hotspot such
behavior is not reproducable.
------------------------------ test.java -----------------------------
import sun.tools.debug.*;
import java.io.*;

class test {

    public static void main(String args[]) throws Exception {
String javaOpts = "-Xbootclasspath/a:"+System.getProperty("java.home") + File.separator + "../lib/tools.jar";
RemoteDebugger d = new RemoteDebugger(javaOpts, null, true);
d.close();
    }
}
