Problems with kaffe 0.8.1

[Yaron Zabary]

Hello all,

  The following code works with JDK 1.0.2 (Solaris 2.5.1), but fails with
kaffe 0.8.1 (FreeBSD 2.1.5). This is a simple server. It just listens to
connections on the specified port. Try to connect twice to this port (I
used a C client, but a simple telnet will do). The second time will fail
with the following message: 

java.lang.NullPointerException
        at java/io/PrintStream.print(line unknown, pc 0x184568)
        at java/io/PrintStream.println(line unknown, pc 0x18508d)
        at java/lang/Throwable.printStackTrace(line unknown, pc 0x184479)
        at Server.main(34)
