Moving to Platform/Resources in case they have seen this before. Otherwise this seems to be NOT_ECLIPSE.

Looks like a problem with the JRE or class libraries. We are just creating a new instance of java.security.SecureRandom here.
(In reply to comment #3) > 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, Ganeshraj.S
