JHipster+consul rate-limit with prod profile throwing ClassNotFound exception. #7178

Puneetsri · 2018-02-26T22:09:06Z

***Apologies if this is not the right project to create the issue in.

Overview of the issue

JHipster+consul rate-limit with prod profile throwing ClassNotFound exception.

Motivation for or Use Case

I am using typical JHipster[4.14.0] microservices stack [brand new project, generated using jhipster generator] (JHipster Gateway + UAA + 2 microservices + consul[0.9.3]). Postgres as database and Hazelcast is enabled in project. My aim was to test the rate-limiting feature. Using 'dev' profile, rate limit is working fine in JHipster, I've tested it successfully, without any exceptions. Now I'm testing it with 'prod' profile. I've enabled rate-limiting in application-prod.yml, added limit + duration-in-seconds(as in application-dev.yml):

gateway:
    rate-limiting:
        enabled: true
        limit: 3
        duration-in-seconds: 30
    authorized-microservices-endpoints: # Access Control Policy, if left empty for a route, all endpoints will be accessible
        app1: `/api`

But while running (tried in intellij with prod profile, tried on command line with -Pprod, also tried with docker-compose with prod profile), it throws following exception:

Reproduce the error

Yes it is highly reproducible. I however have noticed that sometimes when i kill the gateway (when the services are up) and start it again, calls start working [but not always]. It seems to me that there is some kind of race condition. Issue might be between Hazelcast and bucket4j.

Related issues

Not sure but may be related with hazelcast message serialization which does not find the bucket4j class which is probably in a different class loader?
hazelcast/hazelcast#8972???

Please note that I've even created one more project with same configurations, with no db at gateway. Again, in dev profile, rate-limit check is working fine. But in prod, i am getting the same exception ('ClassNotFound') as mentioned above. If i disable the rate-limit, everything is fine(of course i lose the rate-limit feature) in both the projects. There seems to be something special in prod profile+rate-limit, as i never have this issue in dev profile+rate-limit.

jdubois · 2018-02-27T09:53:09Z

Very strange - did you also check with the Bucket4J project? They're doing the integration work here, so the issue might be on their side, and maybe they already know about it

Puneetsri · 2018-02-27T10:13:38Z

@jdubois It more seems to be related to hazelcast: hazelcast/hazelcast#8972.
As I have the bucket4j-core & bucket4j-jcache present in pom.xml of gateway which does contain the class it is complaining about [io.github.bucket4j.grid.jcache.ExecuteProcessor], probably there is some class loading issue with hazelcast, some kind of early checking of type which is causing it to fail. Do you recommend me to create an issue on their side?

Puneetsri · 2018-02-27T20:12:34Z

Can someone please let me know if on 'prod' mode, we start hazelcast & gateway on seperate JVM's? My setup is a single machine setup (one node only) and i think this is not the case by default which is logical.

jdubois · 2018-02-27T20:46:35Z

No everything is on the same JVM - in fact I'm not aware of any big difference between dev and prod mode here! That's why this is strange.

jdubois · 2018-03-06T23:11:24Z

I just tried it on the current master branch, using your .yo-rc.json and running the gateway + a microservice using ./mvnw -Pprod and I had no issue at all.
The master branch is using Spring Boot 2 and we have upgraded many libraries, so we probably "solved" it without knowing it. Can you try again, either on the master branch, or as soon as we do a release?
We'll re-open it if needed, but at the moment I'm closing this as it works on the master branch.

OK I got it, I think, so I'm reopening it.
If you run with with Docker, we have a strange bug, which makes that the gateway tries to be in the same Hazelcast cluster as the microservices. This doesn't happen if you run mvn -Pprod and is clearly a misconfiguration.
So when it tries to replicate a Bucket4J class in Hazelcast, the microservice will fail as it doesn't have Bucket4J in its classpath.

I just fixed it, for the record: when I coded this initially, I didn't think there was an interest in this, as you are doing distributed rate limiting on the gateway + using Traefik (so 2 technologies doing the routing). But that was of course a bad idea (typically Traefik doesn't do rate limiting).

Thanks a Lot @jdubois, when it will be available for use? BTW i did not use Traefik, but just consul (instead of JHipster Registry).

It will be in the next JHipster 5 release for sure.
For the 4.x maintenance branch I can't guarantee - this can probably be cherry-picked to that branch, and then we could do a specific release, but we're lacking time for this.

jdubois · 2018-03-07T20:44:42Z

I cherry-picked it here: 4ac275a

So it should be in the next 4.x release (but I can't tell when we will do that)

Puneetsri · 2018-03-07T20:50:15Z

Perfect, thanks , I'll keep an eye on it. Just a question : Is JHipster 5 release planned in coming 2/3 months? I'm not really sure about the general timelines for JHipster releases, could be helpful to know.

jdubois · 2018-03-07T21:13:53Z

JHipster 5 should be out sooner, probably 2-3 weeks from now.
And we'll have beta releases very soon.

jdubois · 2018-03-08T10:32:30Z

I'm sorry @Puneetsri but cherry-picking this fix on the v4.x_maintenance branch makes our Travis build fail, and I have no time to work on this. So I'm reverting the commit.
So this will probably only be available on JHipster 5.
