My CDK app adds a Lambda Function. The lambda function is stored as another maven package. The directory structure is as such:

CDKApp
-src
--main
---java

-----JavaCdkStack
--test

----com.mikli
-----JavaCdkTest.java

I can't seem to figure out why this is happening. Any help is greatly appreciated.

     ...

Happening on JDK 11.0.15 and Maven 3.8.6.

We are having the jaxb-runtime in the classpath, so not sure why it's not found.

Can anyone of you share a minimal reproducer-project please? have you looked at the ITs in this repo to spot any differences?
