So you'd increase the size of the image by 75%. Further, that space has to be dealt with by the GC. The compactor may have to move this objects around; so it's certainly overhead. It might make sense for development, especially if you use Igor's include-source-in-the-method-trailer approach. But it doesn't make sense for deployment where the application isn't going to look at the sources anyway. So why put a heavy burden on deploying applications when the current system works, and off loads a substantial amount of memory from the system? > > Uko > > > On 9 Jun 2017, at 10:01, Pavel Krivanek <pavel.kriva...@gmail.com> wrote: > > Hi, > > because during the image bootstrapping all source code is reloaded, it is > all placed in the changes file and the sources file is useless.
