> Please review this change which fixes an issue in revocation checking of 
> CRLs. A certificate's CRL Distribution Points extension can contain multiple 
> Distribution Points (DPs), and each DP can contain one or more references to 
> a CRL. These CRL references are typically specified as URLs.
> 
> If there is an issue fetching one of the CRLs (ex: a network error), the JDK 
> implementation saves the exception, but continues to check for other CRLs, 
> and if no other CRLs can be fetched, it throws the exception.  This was 
> working for the case in which multiple CRL references were in the same DP, 
> but not if they were in separate DPs - in that case the exception was thrown 
> immediately and no further CRLs were checked. 
> 
> This also caused inconsistent behavior when the CRL cache was still fresh, as 
> subsequent attempts would skip the CRL with the network issue (while the 
> cache was fresh) and find the other CRLs, until the cache became stale again 
> (30 seconds). The cache is working correctly though. The problem is that the 
> code should continue to check for more CRLs.
> 
> A new test has been added which exercises both cases above.
