Forge installé, MC planté

Yo,

A mon tour d'être emmerdé par l’incompatibilité forge/java8.
Malgré le fait que j'aie glissé dans mon dossier "mods" le LegacyJavaFixer, rien n'y fait, MC ne se lance pas.
Voici ci-dessous le rapport du "development console", c'est la seule chose que je crois pouvoir fournir.
