6.8.7 / #50208 causing problems in Spring Boot 2.2.6

[SledgeHammer01]

Hi,

Spring Boot 2.2.6 upgraded to Elastic client 6.8.7. Looks like #50208 is causing problems.

I am running on Windows 10 Pro x64 with JDK 11.0.6 and started getting this exception after upgrading.

2020-03-30 12:30:51.549  WARN 58892 --- [O dispatcher 13] org.elasticsearch.client.RestClient      : request [PUT http://localhost:9200/

It looks like you run your app with assertions enabled (-ea flag when running java). This is not recommended for production. Can you run with assertions enabled and check if everything is working correctly?

We use assertions in the client code for testing purposes only in our build.

The stack trace above is from mvn (mvnw) clean install. 6.8.7 fails, 6.8.6 passes. No other changes. 6.8.7 should pass a mvnw clean install test, no?

I also encountered this problem, how do you solve it, thank you

[vinayakmp007]

I have also encountered the same problem.
Issue does not occur for
mvn clean install -DskipTests

@martijnvg any update on this? this happens during a mvn clean install.

We are doing regression tests with SpringBoot and for this we cannot disable assertions...
Is there a workaround?
