[jdt-core-dev] No delivery today for integration

["Philippe P Mulet" <philippe_mulet@xxxxxxxxxx>]

We have queued numerous fairly big changes for release, thus we will not
drop for integration today.
We want to ensure we reach some degree of stability before integration.

Queued changes being released are:
- new syntax error message heuristic
- closing the gap between units and working copies:
    1. compilation unit handle stability
    2. generalization of working copies through model APIs
- new API to force reload classpath
- compiler fix for 38393 (test bench crashed during test process)
