Neo4j not starting on Raspberry Pi (memory issues and java.lang.NoClassDefFoundError)

I am currently trying to install Neo4j on my Raspberry Pi. The installation for the latest version worked great so far. When I tried neo4j start I received this error message but was able to resolve it by setting dbms.memory.heap.initial_size=12m and dbms.memory.heap.max_size=12m and dbms.memory.pagecache.size=1g (allthough that feels wrong to me since my Pi has 8GB of memory):

nohup: ignoring input
2021-01-26 21:54:18.409+0000 ERROR Invalid memory configuration - exceeds physical memory. Check the configured values for dbms.memory.pagecache.size and db>
2021-01-26 21:54:18.436+0000 INFO  Neo4j Server shutdown initiated by request
2021-01-26 21:54:18.437+0000 INFO  Stopped.

Now, when I try to start neo4j I get this error in my logs:

nohup: ignoring input
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.neo4j.configuration.GraphDatabaseSettings

2021-01-26 22:20:55.290+0000 INFO  [o.n.s.CommunityBootstrapper] Stopped.

I have now been trying to google the problem for a couple hours but I feel like I don't really know what to look for.

After some more trying it seems like it is a problem with the latest Neo4j version (4.2.3). I now installed version 4.0.11 and it works without any problems.
