I have a spring boot application based on reactor but it can't be launched on Window 10 although it works fine on Linux. It failed to start Netty. This application uses spring boot 2.5.13 now. This issue doesn't exist for the old spring boot 2.3.
The exception was thrown by reactor.core.publisher.BlockingSingleSubscriber.blockingGet.
Is there any config change that could fix this problem? So far, it looks to me like that this problem came from the reactor library and I can't fix by any config change.
Here is the exception stack.

As I understand spring boot 3.0 use Servlet Api 6.0 which is not supported by Jetty and it requires downgrade Servlet API to 5.0.0
(https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0-Migration-Guide#jetty)
To solve this issue, you need to add to your gradle.build script
ext['jakarta-servlet.version'] = '5.0.0'
I'm working in a project which will use PUB/SUB. When I trying to start my springboot App, I received a TimeoutException as shown below.

I'm using Google SDK to set my credentials and project. As well as my application.yml:
gcp:
project-id: ${PROJECT_ID}
pubsub:
topics:
quotesOutputChannel: projects/${PROJECT_ID}/topics/my-topic
subscriptions:
quotesInputChannel: projects/${PROJECT_ID}/subscriptions/my-sub
It happens when I start springboot app.
How can I solve this? I've tried to set pub sub health false on my application.yml and it didn't work as well.
on a Linux machine the container runs inside an exception which I don't understand.
With ejbContainer = EJBContainer.createEJBContainer(); the embaddable container will be started.
In the log file I see an exception:

ERROR javax.enterprise.inject.spi.DeploymentException: couldn't start owb context
Honestly I have no idea what's going on.
Before I found this line:
System.setProperty("openejb.deployments.classpath.include",
".*deltaspike-cdictrl-owb-.*.jar|.*deltaspike-servlet-module-impl-.*.jar|.*deltaspike-servlet-module-api-.*.jar|.*deltaspike-core-api-.*.jar|.*deltaspike-core-impl-.*.jar");
Does anybody have an idea how I can fix this issue?
Thanks,
Markus
One of my colleagues was able to find out the reason.
The regex expression seems to be different between Tomee 7.1.4 and Tomee 8.0.13.
This regex find the libs and solves the probelem.
System.setProperty("openejb.deployments.classpath.include",".*deltaspike.*");

Where is the problem??
Thank you very much!

Since you're running embedded Neo4j this looks like you're missing lucene-core-3.6.2.jar on your classpath.
Best practice is to use a build system supporting transitive dependencies like gradle or maven. For those the most easy this is have a dependency on neo4j-community artifact, e.g. http://mvnrepository.com/artifact/org.neo4j/neo4j/2.2.5. This will pull in all other required jars.
