I'm facing the same problem using the latest compose navigation dependency 2.5.0-alpha03.

You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

Springboot 2.6.0 / Spring fox 3 - Failed to start bean 'documentationPluginsBootstrapper'

Asked 2022-Mar-25 at 06:14

I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.

In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.

I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.

I figured out that these lines in our build.gradle file are the origin of the problem.

ANSWER

Answered 2022-Feb-08 at 12:36

This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.

As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

it's a bug in the library due to a play services update. To fix it, you should explicitly declare that the pendingDynamicLinkData is nullable.

We have a bunch of microservices based on Spring Boot 2.5.4 also including spring-kafka:2.7.6 and spring-boot-actuator:2.5.4. All the services use Tomcat as servlet container and graceful shutdown enabled. These microservices are containerized using docker.
Due to a misconfiguration, yesterday we faced a problem on one of these containers because it took a port already bound from another one.

Since you have everything containerized, it's way simpler.

QUESTION

Criteria for default garbage collector Hotspot JVM 11/17

Asked 2022-Jan-11 at 10:26

I found a source describing that the default gc used changes depending on the available resources. It seems that the jvm uses either g1gc or serial gc dependnig on hardware and os.

The serial collector is selected by default on certain hardware and operating system configurations

Can someone point out a more detailed source on what the specific criteria is and how that would apply in a dockerized/kubernetes enivronment. In other words:

Could setting resource requests of the pod in k8s to eg. 1500 mCpu make the jvm use serial gc and changing to 2 Cpu change the default gc to g1gc? Do the limits on when which gc is used change depending on jvm version (11 vs 17)?

...

ANSWER

Answered 2022-Jan-11 at 10:24

In JDK 11 and 17 Serial collector is used when there is only one CPU available. Otherwise G1 is selected

If you limit the number of CPUS available to your container, JVM selects Serial instead of the defaultG1

JDK11 1 CPU

Any difference between String.getOrElse() and String.elementAtOrElse()?

Asked 2021-Dec-20 at 17:09

As the title states:

Is there any difference between String.getOrElse() and String.elementAtOrElse()? From a functional point of view they seem completely identical, maybe some performance difference?

Same question accounts to String.getOrNull() and String.elementAtOrNull().

ANSWER

Answered 2021-Dec-02 at 06:12

The very links you included in your question allow you to see the source code of each implementation which tells you that, no, there is no difference.

In fact elementAtOrNull literally just calls getOrNull.
