After enabling a service task, then installing it in a project, then for a process (that doesn't even utilize the new work item) a class loading issue occurs. Sometimes it results in UI 'Unexpected error' dialog, sometimes not (couldn't determine the situation).

The service task this issue was filed for: CamelXSLTConnector
Doesn't happen for 'Email' for example.

When accessing the project without the service task installed:

after that when the service task is installed, central restarted and user navigates to Projects page:
