Eclipse is crashing after enabling java security (Java Cryptography Extension - JCE)

Question

Eclipse is crashing after enabling java security. I have added local_policy.jar and US_export_policy.jar into jre/lib/security folder.

I got files from below link :

Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files 7 :http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html

Debug options:

You should add the following to the vmargs section of your eclipse.ini

-Djava.security.egd=/dev/random

Use of /dev/random will likely cause start up delays in your Java application as /dev/random blocks until significant entropy to be generated.

In general /dev/urandom will be a more performant and equally secure source of randomness. Because of Java peculiarities, the vmarg will actually look like:

-Djava.security.egd=file:/dev/./urandom

However, it is unclear to me why this property is required at all. The accepted answer works but gives no indication as to why. I'd be interested to know the cause of the exception.
