Seems like the security policy of the JRE is too restrictive:

I would assume this exception would occur with every eclipse editor.  
Moving to Platform/Resources in case they have seen this before.  Otherwise this seems to be NOT_ECLIPSE.

Any idea how to change it?
"-D java.security.egd=/dev/random" entry in eclipse.ini file will resolve this issue?

Looks like a problem with the JRE or class libraries. We are just creating a new instance of java.security.SecureRandom here.

Yes this is related to JRE. Please go ahead and close this bug.
Now I am able to save the files using eclipse editors.

Thanks for your replies.

Thank you,
