And i do not use serverlove at all 
.
After upgrading to 2.13-SNAP there is no more jcloud's settings on jenkins->config page, although clouds present on jenkins_page/computer (slave node list). Tried upload hpi manually to disk and from jenkins UI - same result.
Only "JClouds BlobStore" settings visible on config page.

Only "JClouds BlobStore" settings visible on config page. Weird indeed.
Like with the other problem,I suspect, that this is triggered by some classloader versioning problem related to guice or guava libs.
I have tested ok on latest LTS (2.32.2), but maybe you have some different set of plugins (which might interfere). Can you please post your plugin version list?
The easiest way to create such a list is by using the jenkins jcli on the commandline:
java -jar jenkins-cli.jar -s http://your.jenkins.url/ list-plugins > pluginlist.txt
Edit:
I hav created a different test version. Please try this one:

added a comment - felfert Thanks! Now it create cloud instance and no more exception thrown. Still not sure about correct work. Will investigate it more closely tomorrow. Thanks again.

added a comment - Do you need a list of my plugins still? Yes please. I could setup an identical local jenkins here in order to reproduce and understand the original error (Note: Until now, I can not reproduce it here).
Vil Surkin
added a comment - Sure, here it is: jenkins-list-plugins.txt
https://www.fritz-elfert.de/jclouds-jenkins-2.13-SNAPSHOT-571e1296-felfert.hpi - this version works well.

Based on that, I'm now going to release 2.13. Expect it to appear on the official jenkins update site soon...
