Introduction

Hosted mode currently takes too long to start up. A significant portion of this startup time is in compiling from source. Instant Hosted Mode proposes to make use of existing class files where possible.

Work in progress

Considerations

• 
  JSNI is not preserved in class files, so we will still need to read from source. We can however, save the JSNI to a file and reuse it if the source file has not changed.
  


• 
  It isn't clear how super-source fits in.
  


• 
  External bytecode rewriting tools, such as emma, need to be considered.
  


• 
  The current generator API makes some aspects of this more complicated, so it might be useful to alter the API (and might be combined with other ideas for allowing generators to run outside a GWT compile)
  


• 
  Method parameter names are not generally available (though it might be possible to use debug information to get them), and some generators require them.
