posix.getpid() does not work in OracleLinux with ksplice #114

Milestone

Installation of jython fails on a OracleLinux 7 system with the "unbreakable enterprise kernel" with ksplice enabled.

After some digging we found that jnr has issues obtaining the process id and also some weird things happen to obtaining file handles.

For instance if we execute the simple Java test on a OL7 with kernel 3.8.13-118.20.3.el7uek.x86_64 we get a result of 0.

POSIX posix = POSIXFactory.getPOSIX();
System.out.println(posix.getpid());

I created a very basic test harness to reproduce this problem here. There are also some straces on a system with ksplice and one without included.

Anyone came across this issue?
