Are you able to solve this? This happened to me also(on mac once) at that time i just thought some problems while creating .keystore file. SO I created one keystore file again with proper values. And then it was working. – Armington

@R.j., I had to create a new keystone from scratch and then it worked. I unfortunately had to discard my previous keystore. – Assured

Answer 1

You get this exception when you specified too big value for validity. Keytool does not do a great job on input validation when creating the keys and then it is not able to read the generated keystore. It is better to keep a backup from the keystore.
