When blueocean (UX) plugin is installed from experimental update center, during install it gives error due to certain plugin not able to resolve guice dependency as other plugin injecting instance is not loaded yet. This happens with 'Install without Restart option'. After restart this error goes aways as Jenkins in this case resolves dependencies correctly.
