Request for Review: 7193792: sun/security/pkcs11/ec/TestECDSA.java failing intermittently

[Jason Uh]

Could I please get a review of:
http://cr.openjdk.java.net/~juh/7193792/webrev.00/

Bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7193792

This change fixes sun/security/pkcs11/ec/TestECDSA.java, which fails on 
Solaris due to what seems to be an unintended back-to-back call to 
Signature.initSign(privateKey). On the second initSign, the test fails 
with CKR_OPERATION_ACTIVE, which means:

 > There is already an active operation (or combination of active
 > operations) which prevents Cryptoki from activating the specified
 > operation. ...

Thanks,
