This works fine on Linux. However, on Mac OS X, the getProcessMaps() method throws an IOException. The exception message is "No such file or directory". I'm using the same version of the JDK on both platforms. I tried using the same version of the JDK on Linux and Mac OS X, but the Mac OS X version of the JDK doesn't even have the LinuxVirtualMachine class. I also tried using the JDK 6 version of the JDK on both platforms, but the LinuxVirtualMachine class is not present in that version of the JDK either. I was wondering if anyone knew of a way to read a process's /proc/$pid/maps file on Mac OS X. I tried using the ProcessBuilder
