Can you try setting the Java version to Java 8? Not sure if it will help.

Re: Seeing issues with unit tests

[Siddharth Pandey]

Sure!
I was using ./gradlew test while trying to run the unit tests.

sipandey-mn1:samza sipandey$ echo $JAVA_HOME

does not seem to return anything. However, java --version returns the
following -

sipandey-mn1:samza sipandey$ java --version
openjdk 17.0.5 2022-10-18 LTS
OpenJDK Runtime Environment Microsoft-6841604 (build 17.0.5+8-LTS)
OpenJDK 64-Bit Server VM Microsoft-6841604 (build 17.0.5+8-LTS, mixed mode,
sharing)
sipandey-mn1:samza sipandey$

Thanks!
Siddharth

Re: Seeing issues with unit tests

[Katie Liu]

Hi Siddharth,

Can you share what commands you are using to build beam? And also share
your Java versions? For example echo $JAVA_HOME?

Thanks,
Katie

Re: Seeing issues with unit tests

[Siddharth Pandey]

Apologies, I forgot to introduce myself :)

I am Siddharth, I have been working at LinkedIn for around a year now and
have been using Samza for one of my projects at work, which got me
interested in wanting to learn more
about the codebase and how it all works under the hood.

Would also appreciate any advice on how I can get familiar with the
codebase and if there are any tasks a newbie can pick up to start with

Thanks!
Siddharth

I can try making the constructors public but wanted to check how have you
