ADDITIONAL SYSTEM INFORMATION :
RHEL 8.3

A DESCRIPTION OF THE PROBLEM :
With open jdk 1.8.0.292 we can correctly access certificates having signature SHA256withECDSA for all the curves
For the certificates that are signed by a root certificate, we see the NoSuchAlgorithm exception => we tried using SunEC, BCFIPS and BC providers

Caused by: java.security.NoSuchAlgorithmException: no such algorithm: SHA256withECDSA for provider SunEC
