code review request, CR 7167988 PKIX CertPathBuilder in reverse mode doesn't work if more than one trust anchor is specified

[Xuelei Fan]

Hi,

Please review the fix for a synchronization issue of JSSE.

webrev: http://cr.openjdk.java.net./~xuelei/7167988/webrev.00/

Cause of the issue: the reverse build did not check for the next trust
anchor even if the certificate path is not complete.

Thanks,
Xuelei
