Description
###@###.### 2003-10-17

When running CORBA tests against S1AS 8.0 certain tests used to hang intermittenly - bug 4913449 . On investigation the cause of the hang was narrowed down to java.net.Inet4AddressImpl.getLocalHostName . See bug 4913449 for more details, thread dumps and a simple test to reproduce the problem.
Comments
EVALUATION This is unlikely to be a JDK bug. Inet4AddressImpl.getLocalHostName() just calls the OS gethostname() function. If this function hangs then it is almost certainly an OS issue. I could not reproduce it on Win2003, though it is probably timing dependent. See bug 4653680 for a similar report. Can you reproduce this on Linux, because we have not seen this on any OS other than Windows so far? ###@###.### 2003-11-26
