Automatically refresh GWT UI on each page load
This came out of frustration while working on the ChangeScreen2 work.
For some types of UI work it can be easier to leave the Jetty server
running and simply click reload in the browser to recompile the GWT
code and load the new JavaScript.
GWT Jetty
-------------
server startup 6s 1s
initial request 20s 39s
no-op reload 10s 7s
The real win comes from changing class structure in the GWT UI code.
None of the UI classes are loaded into the Jetty server so there are
no class schema compatibility issues. In the hosted mode debugger the
developer must exit the debugger and restart it, bringing the edit-test
cycle to significantly longer than the time it takes to run Buck.
Another benefit is testing runs with a real browser, which can show
different results in JSNI code than in the hosted mode debugger.
Events and navigation is faster too, thanks to everything running
natively in the browser. Overall this can make the UI development
experience much less frustrating.
