I had a chance to clone the illumos zone to a separate server and upgrade postgres to latest 10.5. The results are the same: Postgres logs "could not accept SSL connection: ccs received early" The Java code throws the exception: Exception in thread "main" org.postgresql.util.PSQLException: SSL error: Received fatal alert: unexpected_message at org.postgresql.ssl.MakeSSL.convert(MakeSSL.java:42) at org.postgresql.core.v3.ConnectionFactoryImpl.enableSSL(ConnectionFactoryImpl.java:435) at org.postgresql.core.v3.ConnectionFactoryImpl.tryConnect(ConnectionFactoryImpl.java:94) at org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(ConnectionFactoryImpl.java:192) at org.postgresql.core.ConnectionFactory.openConnection(ConnectionFactory.java:49) at org.postgresql.jdbc.PgConnection.

Debugging SSL problems is not really something I do regularly, but you may want to see if changing the settings in the java.security policy helps. Settings to try are: jdk.tls.disabledAlgorithms jdk.certpath.disabledAlgorithms For reference: Java 8 Update 31, disabled SSLv3: http://www.oracle.com/technetwork/java/javase/8u31-relnotes-2389094.html , Java 8 Update 51, disabled some cipher suites, and limitations for DH keys where added: http://www.oracle.com/technetwork/java/javase/8u51-relnotes-2587590.html , similar for Java 8 Update 60: http://www.oracle.com/technetwork/java/javase/8u60-relnotes-2620227.html Java 8 update 71 disabled MD5 hash validation of certificates Java 8 update 121 added restrictions on DSA keysize: http://www.oracle.com/technetwork/java/javase/8u121-relnotes-3315208.html Java 8 Update 141 disabled SHA-1 hashes for the certificate chain: http://www.oracle.com/technetwork/java/javase/8u141-relnotes-3720385.html Java 8 update 161 added limitations for DH keys, made some changes to certificate validation and disabled a number of cipher suites: http://www.oracle.com/technetwork/java/javase/8u161-relnotes-4021379.html Java 8 update 171 disabled some ciphersuites: http://www.oracle.com/technetwork/java/javase/8u171-relnotes-4308888.html Mark have a look at certdir in the source code. Setting up the ssl tests is not particularly difficult. Perhaps getting our tests working first might shed some light ?? Dave Cramer [email protected] www.postgresintl.com
