I'm getting "Exception in thread "main" java.lang.ClassCastException: class org.bouncycastle.asn1.pkcs.PrivateKeyInfo cannot be cast to class org.bouncycastle.openssl.PEMKeyPair" when I run vc_subscribe with TLS configured.

Exception in thread "main" java.lang.ClassCastException: class org.bouncycastle.asn1.pkcs.PrivateKeyInfo cannot be cast to class org.bouncycastle.openssl.PEMKeyPair (org.bouncycastle.asn1.pkcs.PrivateKeyInfo and org.bouncycastle.openssl.PEMKeyPair are in unnamed module of loader 'app')

If you encounter the above exception, then your private key needs to be regenerated with the -traditional option using the openssl command as follows.

openssl genrsa -traditional -out broker.key 2048
