Error creating bean with name 'instancesProxyController' defined in class

[bhagyaperera123]

I upgraded my spring boot application with below configuration.

Spring boot 2.0.4.RELEASE to 2.1.0.RELEASE
OpenJDK 8 to OpenJDK 11
Spring boot Admin version is 2.0.4

before that my application worked well. but now i have bean creation error. below i attached my stack trace.

few months ago i had this error. after that i found my issue. i had two beans with same name.
I have 'InstanceRepository' interface and spring boot admin have same name bean.
then i added this annotation parameter in my project after that my project worked well. ( defaultInstanceRepository )

@Repository("defaultInstanceRepository")
public interface InstanceRepository extends JpaRepository<Instance> {
}

but now i have this problem again after upgrade spring boot , spring boot admin and java.

i know my explanation is not good. sorry about that.

[bhagyaperera123]

actually this error not related with my InstanceRepository interface. i created new project i added spring boot admin configuration and then i ran. i have same error with this project. ( Bean names are different but same error)

java.lang.NoSuchMethodError: reactor.retry.Retry.retryMax(I)

The error is occurring because the version of Spring Boot Admin that you are using is not compatible with the version of Reactor that you are using. retryMax's argument was changed from an int to a long in this commit which is not binary compatible. Unfortunately, I think you'll either have to wait for a new release of Spring Boot Admin that's been compiled against this version of Reactor or for a new release of reactor-extra that restores binary compatibility with earlier versions. /cc @simonbasle @joshiste

Failed to determine a suitable driver class

This is a separate problem and typically occurs when you do not have a database driver on the classpath. If you'd like some more help tracking it down, please come and chat on Gitter or ask on Stack Overflow.

We are going to release a new version of SBA next week which doesn't suffer from this issue until then you can use on of our snapshot versions.

[wilkinsona]

Thank you, @joshiste. Sorry for the trouble caused by the binary incompatible change. Was it intentional, @simonbasle? Is there some documentation that we could link to in Boot’s release notes?

[bhagyaperera123]

I understand! thank you so much both of you!

[simonbasle]

@wilkinsona yes there was a deliberate decision to make this one of the (thankfully few) binary breaking changes in 3.2.0 (or rather Californium release train's first GA).

It is documented in the release notes, the rationale being that having an int there effectively limits the possible number of retries by a significant amount compared to a long (and also, core uses long). The introduction of the indexed() operator in core also made that change possible at a convenient time (version switch).
