BootstrapApplicationListener.CloseContextOnFailureApplicationListener missing method implementation

[gsbtech]

Using

      <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-starter-openfeign</artifactId>
     <version>2.1.1.RELEASE</version>

        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-context</artifactId>
       <version>2.1.1.RELEASE</version>

does not work with spring.boot 4.3.18+ or 5.x
because class org.springframework.cloud.bootstrap.BootstrapApplicationListener.CloseContextOnFailureApplicationListener does not implement method SmartApplicationListener.supportsSourceType()

Current spring 5.1.6, org.springframework.context.event.SmartApplicationListener
still shows the method in question.
https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/context/event/SmartApplicationListener.html

Please show all your dependencies, you have an incompatible version of Framework

[gsbtech]

Using springframework 5.0.8.RELEASE. I also tried older 4.3.18.RELEASE
Here is mvn dependency:tree:

tree.log

[spencergibb]

Spring Cloud Greenwich (2.1.x) is not compatible with spring boot 2.0.x and spring framework 5.0.x. Either update spring boot or downgrade spring cloud to Finchley.

[gsbtech]

What version of spring framework is
Spring Cloud Greenwich (2.1.x) compatible with?
As mentioned in first message in this posting I checked spring 5.1.6, and cloud still had that problem

Current spring 5.1.6, org.springframework.context.event.SmartApplicationListener
still shows the method in question.
https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/context/event/SmartApplicationListener.html

Do you mean that a different path to spring boot will not trigger
org.springframework.cloud.bootstrap.BootstrapApplicationListener.CloseContextOnFailureApplicationListener?

[spencergibb]

Can you provide a complete, minimal, verifiable sample that reproduces the problem? It should be available as a GitHub (or similar) project or attached to this issue as a zip file.

If so, we can reconsider reopening the issue.

[gsbtech]

Let me see if I can write a tiny example with spring 5.1.x

[gsbtech]

We are using a wrapper around spring-boot, so it will take me some time to generate a demo.

Bottomline, this error reported is very straightforward. There is no need for a demo.

Inner Class
org.springframework.cloud.bootstrap.BootstrapApplicationListener.CloseContextOnFailureApplicationListener does not implement method SmartApplicationListener.supportsSourceType() where SmartApplicationListener is the interface that it implements.

So any code using CloseContextOnFailureApplicationListener will definitely fail, because class CANNOT be instantiated (becomes kind of abstract).

Other solution is to deprecate CloseContextOnFailureApplicationListener if applicable.

[spencergibb]

But that only happens when there are incompatible versions on the classpath.

[gsbtech]

spring-cloud 2,1,x should work with spring 5.1.x and probably also spring 5.0.x according to the release.
Just look at SmartApplicationListener from any 5.x, all flavors have the method that the cloud inner class org.springframework.cloud.bootstrap.BootstrapApplicationListener.CloseContextOnFailureApplicationListener does not implement.

[spencergibb]

Spring Framework 5.x requires java 8. Java 8 supports default methods in interfaces:

Spring Cloud 2.x+ also requires java 8.

https://github.com/spring-projects/spring-framework/blob/42fc4a35d59a37131bfe15d029738ab25f358241/spring-context/src/main/java/org/springframework/context/event/SmartApplicationListener.java#L49-L51

[gsbtech]

Java 8 is being used.
I see the default in 5.1.x but not in 5.0.x. Sorry, I missed this, I looked at the Javadoc and missed the"default" qualifier.
The Release Notes seems to indicate that spring boot 2.x is supported.

https://spring.io/blog/2019/01/23/spring-cloud-greenwich-release-is-now-available

The Spring Cloud Greenwich release train is considered a minor release and will continue support for the Spring Boot 2.x release branch.

Probably need to update Release Notes.

Thank you. I see I need spring boot 2.1.x.
