[tor-talk] Fixing Orchid (again), need help!

Hi,
Seems I could fix Orchid.
The problem is neither Tor nor Orchid, seems the list of OpenJDK's
CipherSuites has been changed (I'm using Debian's OpenJDK 10).
Currently, Orchid contains the code in
src/main/java/com/subgraph/orchid/connections/ConnectionSocketFactory.java
like:
private static final String[] MANDATORY_CIPHERS = {
"TLS_DHE_RSA_WITH_AES_256_CBC_SHA",
"TLS_DHE_RSA_WITH_AES_128_CBC_SHA",
"SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA",
"SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA",};
Then calls socket.setEnabledCipherSuites(MANDATORY_CIPHERS).
Now I changed this MANDATORY_CIPHERS to the result of
socket.getSupportedCipherSuites() and Orchid works again!
private static final String[] MANDATORY_CIPHERS = {
"TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384",
"TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256",

};
I'm pretty sure I don't need some of (or maybe most of) them, but it
doesn't exactly correspond to the fixed ciphersuite list (torspec
2.1), so need some more investigation.
Best regards,
MH
