Attached is a test class. Download it, compile it and run it on a
machine to see how many files the JVM can open:

javac OpenFiles.java
java OpenFiles

On my MacBook I get:

Too many open files in system
Failed to create tmp file. Already got: 10014

On my Ubuntu system:

Too many open files in system
Failed to create tmp file. Already got: 4087
