RFR: 8373408: SHA1withECDSA is not required for ECDHE and ECDSA

Tue Jan 13 07:55:32 UTC 2026

SunJSSE should not probe SHA1withECDSA signature availably when determining if elliptic curve cryptography is available, as it is deprecated and not required for ECDHE and ECDSA signature schemes. This change removes SHA1withECDSA from the EC availability probe. TLS signature scheme availability is validated later during handshake negotiation.
