Eclipse deadlocks completely while saving the source file after I've added a data-binding from a checkbox to a member in a model object. Taking a thread dump using JVisualVM shows the main thread being stuck here:

Unchecking the preference setting "Format source code (and reparse) on editor save" prevents the deadlock.


Reproducible: Always

Steps to Reproduce:
1. Select "format source code (and reparse) on editor save"
2. Add a data-binding between a widget and a model object. (I haven't tried different widgets or model objects, but since the problem disappears with changing the preferences as described above, I guess that won't matter.)
3. Save the file. (Not completely sure if this step is necessary.
