Generator-jhipster: /api/profile-info leads to 500 Error

[mathisloge]

Overview of the issue

I´ve created a gateway, one microservice and one uaa-server. The url "/api/profile-info" leads to a 500 Error at every application.

Reproduce the error

Create new blank application. Run it with Gradle

Suggest a Fix

In com.myapplication.application.web.rest.ProfileInfoResource. If I make the Class ProfileInfoVM public, it works as expectet

That's very weird.... As your setup is quite complex, it's bit though to reproduce: could you copy/paste the stacktrace you have on your application? As it's a 500 error you should have a stacktrace.

For sure:

[jdubois]

This is definitely very very strange.

• Do you confirm ProfileInfoVM is inside ProfileInfoResource?
• Did you change anything to what was generated?
• How exactly do you run your application? For example, to you run it from Gradle?

[mathisloge]

• yes i´ve nothing changed from the gernerated code.
• this was a fresh generated application

I use IDEA Ultimate and just run it with idea (Run) it starts normal and connect over consul with other microservices.

Consul, MySQL and Kafka are running in docker.

To configure IDEA i went through the doc (http://www.jhipster.tech/configuring-ide-idea/)

[gmarziou]

So you mean that this error occurs only when running your app from gradle and not from IDEA?
Could you paste output of gradlew -v

Oh you are using Java 9!!!!! We didn't test this at all, I'm surprised your server even started!
That's also very surprising an inner class doesn't work anymore in Java 9.
So just switch back to Java 8 and it will work :-)

[mathisloge]

oh yeah, didn´t see this. In IDEA => Project Structure i´ve choose JDK8. So i´ve think that this will be enough :)

[gmarziou]

Yeah, this is why I asked this. ;)

[mathisloge]

@gmarziou @jdubois i´ve just checked with java8. But even then comes the 500 error, which I described at the beginning. Making the ProfileInfoVM class public fixes the problem for me.

[kaidohallik]

One my coworker encountered similar problem in Windows, error caused by Java 9.
We configured gradle to use Java 8 but that wasn't enough, beacause after compiling, at runtime, it still used Java 9.
We didn't find quick solution with leaving Java 9. As he actually didn't need Java 9 then he uninstalled Java 9. After that all worked as expected.
This is one possible workaround (if you don't need Java 9).

[mathisloge]

@kaidohallik i've just uninstalled java9 but it did'nt make the trick. also I've recompiled the whole project.

[jdubois]

I just tested with your provided .yo-rc.json configuration:

• Your configuration is extremely strange. You're doing an UAA server, why do you add Kafka, Elasticsearch, Hazelcast to it? You can of course do it, but that's definitely not a normal configuration for a UAA server
• I launched the server using ./gradlew (after starting all the Docker instances!), and then hitting http://127.0.0.1:9999/api/profile-info works without any problem. So I just can't reproduce.

[mathisloge]

Strange.
Maybe im just setting it new up without kafka and elasticsearch.

thanks. I think it can be closed due to irreproducibility?

[deepu105]

Do let us know if you find anything interesting here.

[jdubois]

Another thing is that I'm testing with the current master branch (I'm preparing the next release - that's also why I'm happy to test strange configurations!!), so maybe there was something corrected between versions, but I really don't know what it could be. Next release should be out on Friday, you could give it a try.

[mathisloge]

@jdubois checked with version 4.12.0 with the same configuration. Cant reproduce this anymore.

[jdubois]

Ok Thanks for telling us!
