I am trying to use kotlin/jvm with neo4j and I end getting MalformedClass Name Why is this?

[Stephan Schroeder]

More information is needed here. Can you give us maybe the first 3 lines of the stacktrace?

Somehow kotlin generate class names which aren't acceptable by the JVM. I am getting the following runtime error.
kotlin 1.3.72

Can you set a breakpoint at DomainInfo.java:81 and see what the classname is?

[andylamax]

After setting a breaking point. I managed to track down the problem (more of avoid the problem). It seems there is a third party lib (looks like it's build by scala) that has a class that doesn't fit to the java standards. So, I just made added my package to narrow down neo4j's scope for mapping classes
