neo4j 3.3.0 - problems in unmanged extension :-(

[TzvikaL]

first problem:

i wrote an unmanaged extension for 3.2.3 and its work - including the tests.

the i change the neo4j veersion on the pom.xml to 3.3.0

and the tests got this error:

so i skip the tests and build the jar, place the jar on plugin folder and config  with the "dbms.unmanaged_extension_classes" thing like i do on the 3.2.3 version.

then i run bin\neo4j.bat console and i got this error:

any solutions?

[Michael Hunger]

Can you share your pom.xml

You should only have a dependency to neo4j-server (provided)

and neo4j-harness for testing.

See the docs.
