A DESCRIPTION OF THE PROBLEM :
We have trouble in developing a large web-application on Mac OS X after switching from Java 1.6 to Java 1.7. When the application is running in tomcat it is not possible to open new Socket connections. We are 8 developers having the same problem. All attempts to solve this problem by adjusting Mac OS X system preferences for open files etc have no effect.

The problem only occurs on Mac OS X, not on Linux with the same jdk version.

We found a way to reproduce this behavior in a little script.
