Do you get the same results if you put a System.gc() after your thread =
spawn? Perhaps you are just out-running the garbage collector.

I tried this on the diablog-jdk 1.5 on amd64 bsd and it runs quite =
nicely unmodified.

[sam@bob ~]$ java -version
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build =
diablo-1.5.0-b01)
Java HotSpot(TM) 64-Bit Server VM (build diablo-1.5.0_07-b01, mixed =
mode)
[sam@bob ~]$=20

Subject: Memory leak in 1.5.0 JVM
=20
Hello there freebsd-java,

I am running a binary downloaded 1.5.0 JVM on a FreeBSD 5.5 system:

(167)rover:~/levinc/memleak>java -version
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build =
diablo-1.5.0-b01)
Java HotSpot(TM) Client VM (build diablo-1.5.0_07-b01, mixed mode)
(168)rover:~/levinc/memleak>uname -a
FreeBSD rover 5.5-RELEASE FreeBSD 5.5-RELEASE #4: Sat Nov 17 12:13:24 =
PST 2007 mika@rover:/usr/src/sys/i386/compile/ROVER i386

I have found the following program to leak memory on FreeBSD, but not on =
Windows with same Java 1.6.0, nor on Debian with gij 1.4.2:

class Leakq {

private static class MyThread extends Thread {
public void run()=20
{

}
}

public static void main (String[] args)
{
for(; {
(new MyThread()).start();
}
}
}

Best regards,
Mika Nystrom
