Problem getting Java Streams in HP Tandem (Non-Stop)

Question

We are porting a simple Java application between Tandem NonStop systems, from G-Series to H-Series. Java version is 1.5.0_02.

When performing basic I/O tasks like getting output stream from or opening a client socket, we receive exceptions like

java.io.IOException: Value out of range

or

java.net.SocketException: Value out of range

("value out of range" is Tandem native jargon for, well, quite everything I suppose).

Has anybody got similar issues? i.e. I/O corruption while for example messing with JNI?

I suppose there is something wrong with the system, but where might it be?

Thank you.

EDIT:

adding snippets as requested

sample snippet (a) - using Runtime.exec () (adapted)

Properties envVars = new Properties();
Process p = r.exec("/bin/env");
envVars.load(p.getInputStream());

Stack trace (a):

java.io.IOException: Value out of range (errno:4034)
    at java.io.FileInputStream.readBytes(Native Method)
    at java.io.FileInputStream.read(FileInputStream.java:194)

    at java.io.BufferedReader.readLine(BufferedReader.java:362)
    at util.Environment.getVariables(Environment.java:39)

Last line fails, and output gets redirected to console (!).

sample snippet (b) - using HttpURLConnection:

public WorkerThread (HttpURLConnection conn, String requestData, Logger logger)
{
    this.conn = conn;
    ...
}


public void run ()
{
    OutputStream out = conn.getOutputStream ();
}

Stack trace (b):

java.net.SocketException: Value out of range (errno:4034)

  at sun.net.www.protocol.https.HttpsURLConnectionImpl.getOutputStream(HttpsURLConnectionImpl.java:230)

Case (a) can be avoided because it was a workaround for other issues with previous JRE version (!), but same behaviour with sockets is really nasty.

Answer 1

Update: The problem was caused by a spurious .so library.

Answer 2

Error code 4034 seem to indicate that a specific server is not running in your NonStop cluster. Are you sure that your system is setup properly?
