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()
{
}
}
public static void main (String[] args)
{
for(;;) {
(new MyThread()).start();
}
}
}
Best regards,
Mika Nystrom
