Is APOC 3.5.0.16 broken?

[craigknowles]

Hi, several of our devs have been using various Neo4j v3.5.x versions with APOC (in docker containers), and these containers will not start this afternoon. It appears (to me) that the APOC update early this afternoon may be the cause.

The error given is:
Failed to start Neo4j: Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabase@68809cc7' was successfully initialized, but failed to start. Please see the attached cause exception "org.apache.commons.httpclient.URIException". Starting Neo4j failed: Component 'org.neo4j.server.database.LifecycleManagingDatabase@68809cc7' was successfully initialized, but failed to start. Please see the attached cause exception "org.apache.commons.httpclient.URIException".

The full stack trace in the log is below, but does anyone know if that APOC version is causing the issue, and if so if there is an easy way to get the (official Neo4j) docker container to use the 'old' version?

Log (this is for v3.5.20, but we tried with a new v3.5.30 and the same error occurs):

@craigknowles

I'm able to reproduce the same failure with Neo4j 3.5.14 ( simply because I already had it downloaded / installed ) and APOC 3.5.0.16

Let me report to engineering

[conker84]

Hi @craigknowles tomorrow we'll do a new release with the fix.
Thank you so much for reporting this.
Andrea
