Failed to create SSL

[KnowledgeGarden]

Here is the indication:
Jun 06, 2018 9:20:51 AM com.gentics.mesh.example.Server
INFO: Server running on port 3000
io.reactivex.exceptions.OnErrorNotImplementedException: Failed to create SSL connection
at io.reactivex.internal.functions.Functions$OnErrorMissingConsumer.accept(Functions.java:704)
...
Caused by: javax.net.ssl.SSLHandshakeException: Failed to create SSL connection
at io.vertx.core.http.impl.HttpChannelConnector.handshakeFailure(HttpChannelConnector.java:249)

From here I see this:

Most probably because the server you are talking to is not talking SSL. If you haven't specified 443 as the port then your client will be using port 80, so this would make sense.

I can say that I am running mesh localhost:8080 and it is not running on https.

[Jotschi]

I just tested it via:

mvn clean package
/opt/jvm/java8/bin/java -jar target/mesh-vertx-example-0.0.1-SNAPSHOT.jar 

I don't get the error. Thats really strange. Are you sure you use the latest java 8 version to run the example? If you use eclipse you may still use the old run configuration using the old java version?

[Jotschi]

Maybe you missed to toggle the ssl flag to false?

client = MeshRestClient.create("localhost", 8080, false, vertx);

[KnowledgeGarden]

It is true that I was running with 8080, true, vertx; changed to false. Also, had to reconfigure eclipse. Now, new issue: both in eclipse and commandline:
java -jar target/mesh-vertx-example-0.0.1-SNAPSHOT.jar

[KnowledgeGarden]

Perhaps that has something to do with Mesh. I'm going to reboot it now.

[KnowledgeGarden]

Rebooting Mesh changed nothing.

[Jotschi]

@KnowledgeGarden Strange. Are you using the mesh demo? The example only works with the mesh demo.

[KnowledgeGarden]

Yes. It's only a week old but here is what it says on reboot:

Your Gentics Mesh version is outdated. You are using {0.19.2} but version {0.21.1} is available.

[Jotschi]

@KnowledgeGarden How do you start Mesh? Docker? Always make sure to use a tag in that case. Otherwise your docker env may not pull the updates.

docker run --rm -p 8080:8080 gentics/mesh-demo:0.21.1

[KnowledgeGarden]

Running Mesh outside docker. Just downloaded the jar and booted it. I'll go ahead and bring down the latest and boot that.

[KnowledgeGarden]

Same result on Mesh 0.21.1

[Jotschi]

@KnowledgeGarden I don't think this is a mesh issue. Can you post the source of your Server.java in a github gist?

[KnowledgeGarden]

It's precisely what came down from github with the client switched from true to false. No other changes.

[Jotschi]

@KnowledgeGarden And you connect to localhost port 8080? Can you access Mesh on localhost:8080? I tried the same setup and it works without a problem. You could try to replace localhost with 127.0.0.1.

[KnowledgeGarden]

The doctrine of migrating errors is in play. Now we see this:

java.lang.AbstractMethodError: io.vertx.ext.web.templ.impl.HandlebarsTemplateEngineImpl$Loader$1.content(Ljava/nio/charset/Charset;)Ljava/lang/String;

at com.github.jknack.handlebars.Handlebars.compile(Handlebars.java:475)

[KnowledgeGarden]

I get the same error in eclipse and in commandline; with localhost in Server.java or with 127.0.0.1

[Jotschi]

@KnowledgeGarden I'm clueless but I'll ask a co-worker to try the example on his mac. I think something is wrong with your setup/checkout. I'll get back to you.

[Jotschi]

@bernhardriegler Could you please take a look and check whether you can reproduce the problem? I'm clueless.

[KnowledgeGarden]

I may have a different slant on it. I did not checkout the graphql branch. I am starting over with that branch.

[KnowledgeGarden]

This is just the zip download, not opened in eclipse, of the graphql branch (note, the readme for this says to checkout graphql-example branch -- doesn't exist), and I see this result:

INFO: Server running on port 3000

[Jotschi]

@KnowledgeGarden Use the master! - I did not know that the other branch was referenced anywhere. I'll fix the readme.

[KnowledgeGarden]

That takes me back to the previous error messages. Same issue. That's the branch I am running in eclipse, but just to be sure, I'll bring it down again.
