netty4-http producer fails with RejectedExecutionException

[hholtzhausen]

A netty4-http producer is started and stopped immediately during application init. The route
then fails with a java.util.concurrent.RejectedExecutionException when executed.

Producer debug logs during startup:

Can you remove @ApplicationScoped from the route ?

[hholtzhausen]

Same behaviour and exception without @ApplicationScoped annotation.

[lburgazzoli]

last thing the I'll test, can you change quarkus.camel.defer-init-phase from false to true ?

[hholtzhausen]

Tried that to :)

@hholtzhausen this looks like an issue on our side, as confirmation: does it fails in both jvm and native mode ?

[ppalaga]

I can see it failing in JVM mode.

[lburgazzoli]

Seems related to different behaviour of default LRU cache vs LRU cache based on caffeine

[jamesnetherton]

Since you mentioned the LRU cache. I wonder if it's similar to what I observed in CAMEL-13504.

[lburgazzoli]

Yes it is

I was able to reproduce this in native mode a week or so ago using camel-quarkus 0.0.3-SNAPSHOT and quarkus 999-SNAPSHOT. I used those versions to get around #80 and a java.lang.NoClassDefFoundError: org/conscrypt/BufferAllocator during native compile.

With the current camel-quarkus 0.1.1-SNAPSHOT version I am getting the java.lang.NoClassDefFoundError: org/conscrypt/BufferAllocator exception again during native compile. I suspect the NoClassDefFoundError is a problem in quarkus 0.20.0.

[lburgazzoli]

should be fixed now in master
