Good idea. However, even if I change both stderr and stdout to print to
files (see below), the unexpected string still goes to the console,
which suggests that the problem lies in a native library. So there's
probably not much I can do about it, except move to a 1.4 JVM - that'll
have to wait until we upgrade to a 1.4 compatible app server.
Thanks to everyone who has replied.

Al.
import java.io.*;
public class ZipWithComments
{
public static void main(String[] args)
{
try {
System.setErr(new PrintStream(new FileOutputStream("err")));
System.err.println("Test stderr");
System.setOut(new PrintStream(new FileOutputStream("out")));
System.out.println("Test stdout");
new java.util.zip.ZipFile(new File(args[0]));
}
catch (Exception e) {
e.printStackTrace();
}
}
}
Gives the following:
"err": contains "Test stderr"
"out": contains "Test stdout"
Console: "Allocating ZIP comments array...", etc.
