Vaadin and GWT 2.7 compilePerFile

[Artur Signell]

Hi,

There is some issue with -XcompilerPerFile and the generators used in Vaadin. There was a problem with  “stale types” previously, but this was fixed a while back. Today you consistently get a ClassCastException after the first partial recompilation.

SEVERE: undefinedjava.lang.ClassCastException
at Unknown.Throwable_1_g$(com.vaadin.DefaultWidgetSet-0.js@8:8546)
at Unknown.Exception_1_g$(com.vaadin.DefaultWidgetSet-0.js@18:8704)
at Unknown.RuntimeException_1_g$(com.vaadin.DefaultWidgetSet-0.js@18:8745)
at Unknown.ClassCastException_1_g$(com.vaadin.DefaultWidgetSet-0.js@25:154772)
at Unknown.dynamicCast_0_g$(com.vaadin.DefaultWidgetSet-0.js@11:600)
at Unknown.createWidget_0_g$(com.vaadin.DefaultWidgetSet-0.js@12:102047)
at Unknown.getWidget_7_g$(com.vaadin.DefaultWidgetSet-0.js@29:102094)

I don’t have any good way of extracting a small test case so I created https://code.google.com/p/google-web-toolkit/issues/detail?id=8880 already a while back with instructions on how it can be reproduced using the Vaadin project. 

Would be great to get this sorted out before GWT 2.7 - is there anything I can do to help getting this forward?

- Artur
