if I emerge libreoffice without the java use flag I get the following warning:
"If you plan to use Base application you should enable java or you will get various crashes."
If the application crashes without the java use flag, it should be enabled by default.
This only concerns Base, which only a minority of users will care about.
Than it's maybe possible to introduce a "base" use flag which requires java and installs libreoffice base and without this use flag libreoffice base won't be installed.
This way no user "...will get various crashes."
There is no way to split the libreoffice binary, unfortunately. It is always all or nothing.
ok, I think in this case the current state is the best solution.
