Description Chris Laffra

JDT uses at least 3 threads: All Types Caching, JavaReconciler, and Java 
Indexer. For performance monitoring and profiling purposes, these should
be moved to the core jobs facility. 

Currently, the threads run in the background and make calls to 
Display.asyncExec. This makes their behavior difficult to track. If you
really need access to the UI from these threads, use a UI job.

Moving to UI who owns 2 of the 3 items listed.
We already have a record for the background indexer to be surfaced as a true 
job, but we deferred these changes post 3.0 since were too risky at this point.

Kai, can you please comment.

For the all types cache: I am reluctent to change this because this will 
introduce a couple of new dead-lock scenarios.

Not for 3.0.

All type caching is gone since 3.1.
Reconcile is text.
