[Nutch-dev] TestIPC failed

[Stefan Groschupf]

Hi there, 

i can not test the latest checkout from Friday. 
The TestIPC failed on JDK 1.4.2. on os x 10.3.3.

There is a AssertionFailedError at net.nutch.ipc.TestIPC.testSerial(TestIPC.java:145) and a Address already in use exception.

Of course the address already in use depends on my setup, but since this is test class we may be can search for a free port?
Something like:

<x-tad-bigger>private</x-tad-bigger><x-tad-bigger> </x-tad-bigger><x-tad-bigger>static</x-tad-bigger><x-tad-bigger> </x-tad-bigger><x-tad-bigger>int</x-tad-bigger><x-tad-bigger> PORT = 1234;</x-tad-bigger>
<x-tad-bigger>	</x-tad-bigger><x-tad-bigger>/*</x-tad-bigger><x-tad-bigger>
</x-tad-bigger><x-tad-bigger>	 * (non-Javadoc)</x-tad-bigger><x-tad-bigger>
</x-tad-bigger><x-tad-bigger>	 * </x-tad-bigger><x-tad-bigger>
</x-tad-bigger><x-tad-bigger>	 * @see junit.framework.TestCase#setUp()</x-tad-bigger><x-tad-bigger>
</x-tad-bigger><x-tad-bigger>	 */</x-tad-bigger><x-tad-bigger>
</x-tad-bigger><x-tad-bigger>protected</x-tad-bigger><x-tad-bigger> </x-tad-bigger><x-tad-bigger>void</x-tad-bigger><x-tad-bigger> setUp() </x-tad-bigger><x-tad-bigger>throws</x-tad-bigger><x-tad-bigger> Exception {
</x-tad-bigger><x-tad-bigger>for</x-tad-bigger><x-tad-bigger> (</x-tad-bigger><x-tad-bigger>int</x-tad-bigger><x-tad-bigger> i = PORT; i < PORT + 100; i++) {
</x-tad-bigger><x-tad-bigger>try</x-tad-bigger><x-tad-bigger> {
ServerSocket socket = </x-tad-bigger><x-tad-bigger>new</x-tad-bigger><x-tad-bigger> ServerSocket(i);
PORT = i;
socket.close();
</x-tad-bigger><x-tad-bigger>return</x-tad-bigger><x-tad-bigger>;
} </x-tad-bigger><x-tad-bigger>catch</x-tad-bigger><x-tad-bigger> (IOException e) {
System.out.println(</x-tad-bigger><x-tad-bigger>"Port: "</x-tad-bigger><x-tad-bigger> + i + </x-tad-bigger><x-tad-bigger>" in use..."</x-tad-bigger><x-tad-bigger>);
}
}
}
</x-tad-bigger>Make that sense to you?

Has someone a idea how to handle the other problem?
Here my stack-trace.
