Missing cipher in eclipse installer [message #1832823] |

My setup installs plugins from a server that offers only TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256 (ecdh_x25519) and TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384 (ecdh_x25519) as ciphers for SSL. When running the latest eclipse installer the setup fails with an SSL handshake error when accessing this server (tested on macos Catalina, Kubuntu 20.04, and Win10). When I switch to a separately installed JRE in eclipse-inst.ini installation works.
When running the installer with -Djavax.net.debug=ssl:handshake:verbose I get some indication that curve25519 is not supported:
javax.net.ssl|DEBUG|01|main|2020-09-25 09:35:34.234 EDT|null:-1|jdk.tls.keyLimits: entry = AES/GCM/NoPadding KeyUpdate 2^37. AES/GCM/NOPADDING:KEYUPDATE = 137438953472
javax.net.ssl|WARNING|01|main|2020-09-25 09:35:34.444 EDT|null:-1|Signature algorithm, ed25519, is not supported by the underlying providers
Could it be that something is missing from the minimal JRE in the installer that should be there?
