Bug description
Pretty much the same as #211 and #148, but this time with JGit 7.6.0-rc1 (bcprov and related libraries are on 1.82). I'm on Mac OS Tahoe 26.3, using Java Temurin 25 and a id_ed25519 keypair that has worked well for me in the past.
Do I need BC libs at 1.83 or something?
After updating to eclipse 2026-03-rc1 (4.39.0), with JGit 7.6.0-rc1 I cannot do any operations on my GitHub/GitLab remotes. Is this expected?

Actual behavior
No Git remote operation works with my id_ed25519 keypair.
