jconsole certificate error
Raw
jconsole.md

If jconsole doesn't trust the remote server's CA then on Linux it will fail with

Connection failed: error during JRMP connection establishment; nest exception is: java.io.EOFException

On Windows I got this error instead (?):

Connection failed: non-JRMP server at remote endpoint

This is solved by downloading the server's certificate and converting it to a keystore:

true | openssl s_client -connect server.com | openssl x509 > serv.cert
keytool -import -alias serv -keystore serv.jks -file serv.cert

Then jconsole can import it at launch:

jconsole -J-Djavax.net.ssl.trustStore=test.jks -J-Djavax.net.ssl.trustStorePassword='password'
