Hello Sean,
I tried now 1.8.0_152ea b04 (May 2017) and using the keytool works now
again to open the JKS with this broken certificate. It is also possible to
use CertificateFactory.getInstance("X.509").getenrateCertificate(in) with
the questionalble certs.
This is great! From the look of JDK-8175251 it seems it also will show up
in the next CPU.
The same bug also claims its fixed in 131, however it talks about b33 where
the public version is b11. So maybe thats the reason for 131 beeing still
affected?
I suspect the broken certificates will not be useable in a certificate
chain, I will test that later on.
Gruss
Bernd
