ClassCast exception even when using JclUtils.cast() about jcl HOT 3 CLOSED

Apparently it looks like the classloader that is loading jcl-core is different from the classloader that is loading Pager. Are both jcl-core and you Pager api in lib folder of your web app? Is jcl-core or ur api jar also available somewhere else in the classpath?

Try the following to see if it works.

Pager pager = JclUtils.cast(plugin.activate(), Pager.class, Pager.class.getClassLoader());

It could also be a bug, will run a few tests later to see whats going on.

First off, thanks so much for super-quick reply!
You are absolutely correct: I actually had "left" in the JAR being loaded the AlertPlugin/Pager classes: for some reason, it worked with the AlertPlugin, but it didn't with the subsequent Pager; I've manually removed those classes from the Jar, and the command now succeeds.

In a 'realistic' environment, obviously this would not happen, as I'd have an SDK Jar with the API classes, for the plugin to be built against, but that would not be 'carried over' during the upload.

I will now test whether I'm getting (behind the scenes) the same object and will let you know if this all works.

Just FYI (more details in the github repo of the project) I'm using Spring Boot, and building it all with Maven; so there's no such thing as a "lib folder".

Thanks!

PS - please let me know if there are areas you'd like me to test/contribute to: JCL is solving a pretty important problem for my project and I'm a big believer in "giving back".

Wish you all the best.
