[jacob delddd]

Following the tutorial on https://developer.atlassian.com/server/jira/platform/oauth/ i managed get till step 2. 

Running :

java -jar OAuthTutorialClient-1.0.jar requestToken 

 gave me this error:

 Saddly i seem to be the only one. 

jira\_privatekey is named jira_privatekey in my folder, other than that i can't seem to find any differences

also creating the keys didn't gave me any problems:
