Simon Billingsley commented on CURATOR-454:
-------------------------------------------
Yes, I have read that and I am still seeing these compile-time issues.
We initially had issues running curator-test until I downgraded back to 2.12.0
of that (thanks to that wiki page) but this module does not use curator-test.
The module uses curator-framework implicitly as we have written a wrapper
library around curator which depends on zookeeper/curator that is used by this
module.
Here is an extract from the module pom.xml (we include the zookeeper / curator
libraries directly as this is a war which must be deployed):

> Curator 4.0.0 be used with Zookeeper 3.4.10 due to compile-time issues

> Key: CURATOR-454
> URL: https://issues.apache.org/jira/browse/CURATOR-454
> Project: Apache Curator
> Issue Type: Bug
> Components: Framework
> Affects Versions: 4.0.0
> Reporter: Simon Billingsley
> Priority: Major
>
> I see compile issues when trying to compile a project with a library that
> depends on apache curator 4.0.0.
> We are trying to upgrade to a newer version of Zookeeper (3.4.10) due to
> security issues in ZK 3.4.9 and have been forced to upgrade to a newer
> version of curator (from 2.11.1 due to other curator issues) but we keep
> hitting compile-time issues (see below) which mean that we need to use ZK
> 3.5.3-beta at compile time even though we will use ZK 3.4.10 at runtime.
> Here is an example of the javac verbose output (via maven):

> If I look through the source code I see that RemoveWatchesType imports and

> I don't understand how the backwards-compatibility is meant to work. It is
> also strange that this compile error only appears for a few of the modules in
> the project, so it must depend on which classes are used by the library and
> so which classes are loaded into the compile tree.
