AppEngine Standard Java, objectify 5 suddenly asks for init()

[Malte Jäger]

Since last week after launching a new deployment the BootStrapper logs:

(Preconditions.java:444)com.google.common.base.Preconditions.checkState> You must call ObjectifyService.init() before using Objectify

-> This should not be in Version 5 of objectify.

While the same source works when  redeployed - we do not know what is going with some Versions that just dont work.

I'm not quite sure what you're seeing here, got a stacktrace?

If you're getting that message, it sounds like you have the Ofy6 jar on your classpath and are trying to use it. Check your dependencies.

just as we all know there was an additional ofy6 jar ... it was added by "Google Cloud Platform Library" checkmarked "Objectify". I do not know if this was added last week or if it has just been some internal luck it did not produce the error earlier. I removed ofy6 jar and everything is ok. Thank you for your hint :-)

-> AppEngine Standard, Objectify 5.1.24.jar with appengine-api-1.0-sdk-1.9.86.jar <- 

Now a new deployment to the long running production project does not work: "java.lang.NoClassDefFoundError: Could not initialize class com.google.appengine.api.datastore.DatastoreApiHelper".

The same Source runs on a different AppEngine Test Projekt and local. 

I compared all deployed jars of the older running version of the production project and the new deployment to remove any difference. 

The active old version still works. Does a new deployment using Eclipse GCP Plugin  change anything to the way the datastore in production is involved? (i temporaly had a objectify 6 jar deployed in addtion to 5 which i removed).

the log:

Two old Libraries messed all up: appengine-api-labs.jar  / appengine-tools-api.jar

Thos hat the Preconditions repacked with incompatiblility.
