Java web application not binding with Heroku $PORT

I have made a Java web application and trying to host it on Heroku with a Dockerfile, CMD as :
CMD ["java", "-Dserver.port=$PORT", "-jar", "/usr/local/lib/backend.jar", "--server.port=$PORT"]
And getting the logs as follows:
2022-05-06T06:53:33.599532+00:00 heroku[web.1]: Starting process with command `java -Dserver.port\=\27061 -jar /usr/local/lib/backend.jar --server.port\=\27061`

2022-05-06T06:53:41.544514+00:00 app[web.1]: INFO: HTTP-Server started on port 1337
I am not getting able to understand that my argument is providing --server.port=27061 but still the HTTP server is starting on port 1337.
I have already seen all the related available answers on Stack Overflow but none works for me.
I am using javawebstack httpserver

Application throws error on Ubuntu 19 with Java 11

Could one please help me figure out the reason why my application written in Kotlinfails to run after it was built with Intellij Idea and deployed to Ubuntu 19.10 virtual machine ?
I use the following components:
Ktor 1.3.0
Netty for Ktor

Eureka Service fails with exception after client connects

I am following the example from here.
I also have the Eureka server running on localhost:8080.
As a next step I attempt to run the sample service, like this:
./gradlew :eureka-examples:runExampleService
Here is the output that I get:

It basically connects to the server and waits for response, etc.
At the same time on the service terminal I see the following happening. Sometimes when I do these actions I see the successful response on the eureka service:

ERROR:
ERROR: Re-run SonarQube Runner using the -X switch to enable full debug logging.
Can any one help me in finding out error,i am analysing project by setting java heap to 2048m in wrapper.conf i got out of memory heap size,so i tired to set java heap size to 5120 and sonar-runner-opts to 8192 but still its failing at same point,
These are the plugins which i have used abacus,checkstyles,pmd,java,useless code tracker
Database:mysql
Thanks in advance

Check the answer of this question .. it will help you wither to set the memory or fixing the issue of wrong selection with file extension
Sonar - OutOfMemoryError: Java heap space
If your code is to big then you have to break it into modules .. check this

I hope this could help!

Starting cassandra on Solaris (SunOS 5.10 sparc) fails with SnappyError

I have downloaded the DataStax build of cassandra (dsc...-bin.tar.gz) and unzipped appropriately onto a Solaris Server machine. After editing configuration directories in accordance to http://wiki.apache.org/cassandra/GettingStarted/, I tried starting cassandra for the first time using "./cassandra -f" from ~/cassandra/bin, but encounter an exception on startup that results in a stack trace.
The log file is below.
I have installed the same build of cassandra on a windows machine (for testing) but have never encountered this type of error. I'd appreciate it if Cassandra vets could help me out.

The problem is in the cassandra dependencies libraries. Apparently, Cassandra 1.1.2 (which I am using) relies on native methods for Snappy Compression. Cassandra 1.1.0 does not depend on native methods so it works without a problem!
