GWT 2.7-rc1 slow compilation

[GoogleCodeExporter]

Hi. I am trying to use new GWT 2.7.0-rc1 but compilation in IDEA/ECLIPSE takes 
a long time. 
By maven - 2 min, by IDEA/ECLIPSE - 10 min (2 min for 2.6.1)
Compiling starts again and again for each Remote Service.
See attachment to make sure that plugin generates more files than Maven.

Found 3123 cached/archived units.  Used 3123 / 5499 units from cache.
