Is there a defined criteria for when asynchronous tasks are loaded?

see also Defect 169426

I have declare an async task and an operation participant in the same plugin. The operation participant offloads some long running operations to the async task to improve the user experience by not blocking.

If the /ccm web UI has not been visited the async task is not available, meaning that if you start up RTC, and then trigger the operation participant via the IDE, the operation participant fails because the async task isn't available.
