Can'n attach to JVM using remote debug

Question

Hello!
I have some problem. I have create a JVM in C++ program usin JNI. Parameters (reat from conf file):
-Xdebug
-Xnoagent
-Djava.compiler=NONE
-Xrunjdwp:transport=dt_socket,server=y,address=5007,suspend=n
-Djava.class.path=jar_1;jar_2;...;jar_n
JVM is created successfullly. Then I try attach to JVM from IDEA by remote debug with parameters:
-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5007
After this I have get the next error: "Unable to open debugger port: java.net.SocketException Connection reset". And my program is shut down. I can't solve this problem. Maybe anybody have some ideas. Thanks.

Try to debug the next java cod:
public class TestClass {
public static void FileCrt(String str)
DataOutputStream OutStream;
String sOut;
sOut = new String(str);
try
OutStream = new DataOutputStream( new BufferedOutputStream(new FileOutputStream("c:\\output.txt")));
OutStream.writeBytes(sOut);
OutStream.close();
catch (IOException e)
e.printStackTrace();
public static void main(String[] args)
FileCrt("Test");
I have created the test.jar and run it by the command:
java -cp test.jar -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,address=8787,suspend=y testpackage.TestClass
Then I try to connect to JVM by remote debuger (-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8787) and get exception "Unable to open debugger port java.net.ConnectException". What's the problem?
