Down cast of UrlConnection without check in CrlCache (fails in case of FTP CLR distribution) #1867

Closed fejpet closed 1 month ago

fejpet commented 1 month ago

This is a down casting without check throws an exception in case of FtpUrlConnection is used, but this issue is hidden by "CertPathValidatorUtilities.java:785" catch (Exception e) as todo mention a log would be useful.

The SSL connection will fail with following message: "Caused by: org.bouncycastle.jce.provider.RecoverableCertPathValidatorException: No CRLs found for issuer", because the ftp based crl could not be downloaded.

You can reproduce with a certificate which contains an FTP CRL distribution point only.

Weird... I've removed the downcast. Thanks for the report.
